Heads up Notification not working when App is in background

[jerryheir]

I have gone through all the related issues and I cant find any real solution to this. Even the documentation doesn't answer it but points to a google documentation.

The user's activity is in fullscreen mode (the app uses fullScreenIntent).
The notification has high priority and uses ringtones or vibrations on devices running Android 7.1 (API level 25) and lower.
The notification channel has high importance on devices running Android 8.0 (API level 26) and higher.

I HAVE DONE ALL THE ABOVE, I added , but still does not work the way other apps notify me when I am in another app. My code is below.

    const channel = new firebase.notifications.Android.Channel('test-channel', 'Test Channel', firebase.notifications.Android.Importance.High)
    .setDescription('My apps test channel')
    .setSound('default')
    .enableLights(true)
    .enableVibration(true);
    await firebase.notifications().android.createChannel(channel);
    this.notificationListener = await firebase.notifications().onNotification((notification) => {
        if (Platform.OS === "android") {
          notification
          .android.setChannelId('test-channel')
          .android.setSmallIcon('transwr')
          .android.setColor('#BE64FF')
          .android.setAutoCancel(true)
          .android.setPriority(firebase.notifications.Android.Priority.High).setSound('default');
        }
        firebase.notifications().displayNotification(notification);
    });

Please I have done everything
It works in the foreground but when I go to another app, I get the sound and see the icon on the status bar but it does not pop up

Hi
For me the notification is getting displayed when the app is in foreground and background but not when the app is closed. I am using below code in firebase.messaging().onMessage listener for handling notification when app is in foreground and in headless JS when the app is in background. How to make this work when the app is closed?

const channel = firebase.notifications().android
    .createChannel(new firebase.notifications.Android.Channel('test-channel', 'Test Channel', firebase.notifications.Android.Importance.High));
    
    channel.then(()=>{
        let notification = new firebase.notifications.Notification();
        notification.setTitle(message.data.title).setBody(message.data.body).setData(message.data)
        .android.setChannelId('test-channel')
        .android.setAutoCancel(true)
        .android.setPriority(firebase.notifications.Android.Priority.High).setSound('default');

        firebase.notifications().displayNotification(notification);
    });

priorities maybe, https://dontkillmyapp.com maybe, vendor restrictions for intent receiving (check unfiltered logcat) maybe
