<meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@mipmap/notification_icon" />

Subscribe for two signals:

    messaging.connect('token_received', self, '_on_token_received')
    messaging.connect('message_received', self, '_on_message_received')

func _on_token_received(token: String) -> void:
    pass

func _on_message_received(message: Dictionary) -> void:
