Raven Push Notifications and Firebase Integration

I’m currently working on integrating Firebase Cloud Messaging (FCM) to enable push notifications in my app using Raven. I’ve followed the official documentation provided by Raven for Firebase Push integration, including setting up the Firebase project, adding the google-services.json file, updating the build.gradle files, and initializing Firebase in the application.

However, the push notifications are not working as expected — either the device is not receiving the notifications at all, or they are not triggering the intended behavior within the app.

I’ve verified that the Firebase setup is correct, and other Firebase services (like Analytics or Crashlytics) seem to work. But the FCM part specifically with Raven doesn’t seem to function correctly.

Is there any alternative method or library to implement push notifications with Raven, or any known issues or workarounds that might help resolve this?
