Disabling Google Hangout on Google Calendar

If you are using the Zoom Chrome extension, it will overwrite the Where and Video with Zoom. However, on your Google Calendar reminder, a Google Hangout link may still appear and be automatically added to Google Calendar events. Admins can disable this setting for Google Workspace. Users will still be able to add or remove the Hangouts video call links from events, but will not be able to set their own defaults.
