In firebase documentation they say:
With FCM, you can send two types of messages to clients:
Notification messages, sometimes thought of as "display messages." These are handled by the FCM SDK automatically.
Data messages, which are handled by the client app.
It is very easy and straightforward to send notification message through firebase console (I just use Grow => Cloud messaging => New notification).
However there is no such section for data messages, and also documentation does not contains almost any related informations.
How to send data message from firebase console? I dont want to send notification message, because that is basically just a display message handled automatically - I want to send a data message, so I can handle it on my own, inside my app and do something on background
