FCMMessagingService in a clean architecture?

Question

I am developing an application in which I use Firebase Cloud Messaging. And I use clean architecture for my application. I want to know where (in which layer: data, domain, presentation) is the best solution for placing my classes called MyFirebaseMessagingService and MyFirebaseInstanceServiceID? These are my classes: myFirebaseMessagingService:

public class myFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG="MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d("onMessageReceived", "Pozvana funkcija onMessageReceived");
    Log.d(TAG, "From " + remoteMessage.getFrom());
    Log.d(TAG, "Body " + remoteMessage.getNotification().getBody());
    Log.d(TAG, "Location " + remoteMessage.getNotification().getClickAction());
    Log.d(TAG, "Value " + remoteMessage.getData().get("click_action"));
    sendNotification(remoteMessage);
    Log.d("Function called", "sendNotification");


}

private void sendNotification(RemoteMessage remoteMessage) {
    Intent intent = new Intent(myFirebaseMessagingService.this, MainActivity.class);
    intent.putExtra("click_action", "goToFragment1");
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notification=new NotificationCompat.Builder(this)
            .setSmallIcon(logo)
            .setContentText(remoteMessage.getNotification().getBody())
            .setContentTitle("Title")
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notification.build());
    String message=remoteMessage.getNotification().getBody();
    DataBaseHelper db=new DataBaseHelper(this);
    db.insertMsg(message);
    intent.putExtra("poruka",message );
    Log.d("Log>Poruka", message);


}

And this is myFirebaseInstanceServiceID:

public class myFirebaseInstanceServiceID extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {
    super.onTokenRefresh();
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app servers.
    sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
    // Add custom implementation, as needed.
}

I think such classes should be part of what you call the presentation layer.
