Data Model for Firebase/Firestore chat application

Question

This is the current Firebase/Firestore data model I am using for my test chat application. However, this model is very hard to use for push notifications on Android side. I want to send push notifications to users phone when they receive messages from any of the channels they are part of. In addition file/image messages need to be added.

Any recommendations or any examples of good data models for chat applications I can use as a reference.
