I\'m trying to send some data to my users via the new Firebase push notifications service.
I\'m adding some \"key-value\" custom data items with \'Message text\' -
When you application is in the foreground, notifications will be passed to FirebaseMessagingService.onMessageReceived(). When the app is not in the foreground, the notification will be handled by the default notification center.
