unable passing multiple actions to notification action intent

Be informed, we are trying to send notification with a button using Addaction. The button Start has a intent that directly opens a url in a webview, which works perfectly fine with code given below

 Intent intent = new Intent(this, MainActivity.class);
        intent.putExtra("uri", uri);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        //int notification_id = nid!=null ? Integer.parseInt(nid) : MainActivity.ASWV_FCM_ID;

        int m = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
        int notification_id=m;

        Intent buttonIntent = new Intent(this, ButtonReceiver.class);
        buttonIntent.putExtra("notificationId",notification_id);

//Create the PendingIntent
        PendingIntent btPendingIntent = PendingIntent.getBroadcast(this, 0, buttonIntent,0);

        String channelId = MainActivity.asw_fcm_channel;
        Uri soundUri=Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/raw/pristine");


        NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.mipmap.ic_launcher, tag, pendingIntent).build();
        NotificationCompat.Action action1 = new NotificationCompat.Action.Builder(R.mipmap.ic_launcher, "Dismiss", btPendingIntent).build();

            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

NotificationCompat.Builder notificationBuilder1 = new NotificationCompat.Builder(this, MainActivity.asw_fcm_channel)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(title)
                .setContentText(message)
                .setDefaults(Notification.DEFAULT_ALL)
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setAutoCancel(false)
                .addAction(action)
                .addAction(action1)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel mChannel = new NotificationChannel(channelId, "My Notifications", NotificationManager.IMPORTANCE_HIGH);


            AudioAttributes attributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();


            // Configure the notification channel.

            mChannel.setDescription("Common notifications");
            mChannel.enableLights(true);
            mChannel.setLightColor(Color.RED);
            mChannel.setSound(soundUri, attributes);
            mChannel.enableVibration(true);
            mChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
            mChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
            notificationManager.createNotificationChannel(mChannel);

        }
        
        
            Notification noti = notificationBuilder1.build();
            noti.flags = Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE | Notification.FLAG_AUTO_CANCEL;
            notificationManager.notify(notification_id, notificationBuilder1.build());
    

Update:

I'm sorry but i'm not actually a expert or a regular coder in android java, so you gotta help me here a little bit more. I have passed on my notification id down in the code, but the problem here is how do i invoke removeNotification in the pendingIntent which also carries my url to where the link will go onclick

Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("uri", uri);
intent.putExtra("notificationId",notification_id);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

public static void removeNotification(int notification_id) {
            try {
                if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
                    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                    notificationManager.cancel(notification_id);
                }
            } catch (Exception e) {

            }
        }

But we also like the notification to be dismissed simultaneously onclick. We tried using .setAutocancel (true) and notification flags like FlAG_AUTO_CANCEL, but the button just does first action right of going into webview url and not cancelling the notification.

Shall appreciate should you help us out.
