* Parse the received data from Push. Json format are different depending on the source.

* Notifications received by FCM are formatted by the matrix gateway [1]. The data send to FCM is the content

* On the other side, with UnifiedPush, the content of the message received is the content posted to the push
* gateway endpoint [3].

* *Note*: If we want to get the same content with FCM and unifiedpush, we can do a new sygnal pusher [4].
