[firebase_messaging] Firebase do not collect opens and conversion data of push notification for ios

[sunghwanJo]

Below is the scenario of the problem

1. Sent iOS notification using Cloud Messaging on Firebase Console
2. Confirmed receipt by clicking the push message
3. Upon confirmation, the app launches

My question regarding the situation above
Can't Firebase track any data related to iOS push notification (i.e. open & converstion rates)
If not, is there any way to track this data?

FYI
AOS data is being collected just fine and displays the result no problem

If there's anyone who's faced similar issues like me,
I'd much appreciate the word of advices or help.
