What if the Notetaker is stuck in the waiting room, but I don't see the pop-up?
If the Google Meet meeting is configured with "Host management" mode enabled, only the "Hosts" will see popups to let participants in from the waiting room.
If none of the Hosts are in the call yet, nobody will see a pop-up to let the bot in.
Participants whose email address is on the event invite are able to join with no host present. So, other invited participants may join before the host and wonder why the bot is not joining.
Once the host joins, then the host will see the pop-up appear. Any signed in participant can let the Notetaker in.
When a bot attempts to join a Google Meet call, this dialog will be displayed to participants:
Can the Notetaker automatically join my meetings in Google Meet?
By default, Google Meet bots need to be manually admitted into calls and will be an "anonymous" user.
If you want the Notetaker to automatically join Google Meet calls, the Notetaker must be Authenticated.
Authenticated bots are still subject to any waiting room settings enabled by the host.
