PDF viewer permission issue in android 11

I am opening pdf file using an external pdf viewer application. But in android 11 shows eacces permission denied issue. All permissions already declared in my manifest file.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        

Also declared this :

android:requestLegacyExternalStorage="true"

Creating and writing the content with below code :

byte [] decodedContent = Base64.decode(base64.getBytes(), Base64.DEFAULT);

                try {

                    File pdfDirPath = new File(getApplicationContext().getExternalFilesDir(null).getAbsolutePath(), "pdfs");
                    File file5 = new File(pdfDirPath, globalData.getVin()+".pdf");

                    if (!file5.exists()) {

                        file5.getParentFile().mkdirs();
                    }

                    outputStream = new FileOutputStream(file5);
                    outputStream.write(Base64.decode(base64, Base64.NO_WRAP));
                    outputStream.close();
               

And open above file like this :

    Uri   path = FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName() + ".helper.ProviderClass", file5);
  intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(path, "application/pdf");
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

Please help me with this.
