This could be due with a vulnerability within the Firebase Cloud Messaging service, more people have reported those notifications.
The same notifications showed up in Google Hangouts last week.

Hi pereiras,
Either way, the notifications themselves should be harmless — the vulnerability apparently only affects Google's notification service, not user accounts or devices.
Currently, Microsoft has managed to put a stop of the rogue FCM notification that have been affecting Teams.
