[firebase_messaging] Is "apns-topic" for Data-Only messages necessary when app terminated in iOS ? What should be its value ?

[ibrahimbroachwala]

This is what the current doc says:
LINK

...
"apns-topic": "io.flutter.plugins.firebase.messaging", // bundle identifier 
...

This configuration provides the best chance that your data-only message will be delivered to the device.

What does bundle identifier mean?

Should be the bundle identifier of my app or it should be io.flutter.plugins.firebase.messaging as mentioned in doc.
