"Teams" tab shows a notification that cannot be cleared.

While using the Mac client there were 3 expired invitations that I was alerted to in the teams tab. I decided to cancel all three of the invitations which cleared 2 of the three alerts. One of the alert notifications is persistently showing in the dock icon and in the app despite reinstalling the app, deleting the cache and other mildly invasive attempts to clear it. The unclearble notification does not show up on the mobile client nor does it show up on my other Mac client (same version).

Mac Version:

Version 5.4.0-20200416160205+e81aee5eaf (5.4.0-20200416160205+e81aee5eaf)

No source files, tests, or entry points are identified. Start by reproducing the persistent Teams-tab notification on the Mac client using the reported 5.4.0 version and compare it with the mobile and other Mac clients; done means the expired-invitation alert can be cleared consistently.
