1. Firebase notifications are integrated in application. Application is receiving the notification for Firebase console, properly without any issue.

2. Turn off notification setting from device setting.

3. Generate a notification from firebase console.

4. Observe that No Notification is displayed in any state in the Notification Center.

5. Turn on notification setting from device setting.

6. Observe that No Notification are displayed but the badge count is getting displayed.
