Using Firebase for Push Notifications not working on App Store application

Hi, I'm having some issues with the App Store application badge on iOS 13 - latest.
I'm using Firebase Cloud Messaging (FCM) as the notifications delivery provider.
If the app isn't uploading to the app store is working, but after uploading notification not working any more.
They are not receiving it whether the app is in foreground or background.

Looking at a log, we're seeing this:

Code Block
401: Unauthorized
at PushNotifications.SendFCMMessage (CallRest : 'Call REST (POST)')
at PushNotifications.SendFCMMessages.nested.f664141d-55a8-4674-aa58-b2cd8e97e0ce [58 of 84] (SubMicroflow : 'SendFCMMessage')
at PushNotifications.SendFCMMessages (NestedLoopedMicroflow : '')
at PushNotifications.SendMessages (SubMicroflow : 'SendFCMMessages')


How can I solve this?
