we are using mesibo_flutter_sdk v2.2.9, it was working normally but after we added firebase_messaging v14.7.20
we found that Mesibo_onConnectionStatus method was no longer getting called after starting mesibo
specifically we found that following line is causing the issue, if we comment it out, it works normally

FirebaseMessaging.onBackgroundMessage(_handleBackgroundMessage);

we have created a minimal reproducible code sample, you can try running it with FirebaseMessaging.onBackgroundMessage(_handleBackgroundMessage); commented out and see that mesibo is working but if we enable that line then mesibo does not work.

we also have added a simple platform channel methodChannelExample with method getMsg which we call when we click on the Floating action button,
it will print hello from method channel in console if the call was successful , this is to demonstrate that even when mesibo is not working, our platform channel works, which disproves the speculation that firebase_messaging v14.7.20 is causing the platform channel to close/terminate or misbehave.
