After performing many tests I realized that the integration ONLY works when the user is inside a team calendar. This does not work for the same user even if Google Meet integration is active. This is EXTREMELY CONFUSING, essentially this integration should work for the user on BOTH occasions, on a personal calendar AND team calendars. Makes no sense to only have it in one, please allow for all users.
Finally after 30 minutes and in found.
I confim this video is confusing, need to be updated! :)
