FCM notification arrives only user opens the device screen (Android 11) in PHP

I have a php page and I want to send push notification to Android devices.

Here is a php code sample what is working:

<?php
function sendPushNotification($to, $data = array()){
    $fields = array('to' => '/topics/' .$to , 'notification' => $data);//, 'android_channel_id' => 'automento_szallitas');
    echo $fields['to'];
    echo $fields['notification'];
    
    //$headers = array('Authorization: key='.apiKey, 'Content-Type: application/json');
    $headers = array('Authorization: key=MY_SECRET_FCM_KEY', 'Content-Type: application/json');
    
    $url = 'https://fcm.googleapis.com/fcm/send';
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
    echo "ok";
}
$data = array(
    'title' => 'title',
    'body' => 'body'
  );

sendPushNotification("myTopic", $data);
?>

I got the notification for the Android device, when the device screen is open. (Android 11 device) I enabled everything and turned of every energy save mode. I can get notification in few minutes from Firebase console whe a scree is locked till minutes. If I use the php code with a 10 minutes screen lock, de notification doesn't arrive. I got it inmediatelly when I open the screen. It seems the front end Android code is ok. I think there is a problem with the back end side php code but I haven't a clue
