They are sending notifications using fcm. The user checked the notification, but the number of badges is not initialized.

This problem did not occur in android. In ios, badges' notifications continue to accumulate and are not initialized. When developing other apps, if you check the app after the notification comes, all the notifications are initialized, but for some reason, the app currently being developed does not initialize, and the number of notifications continues to accumulate on the badge. How can the number of badges be initialized when the user checks the app?
