I'm looking for a way to add shared (read only) calendars from Google Calendar into thunderbird, but I have run into a dead-end. Thunderbird prompts for the calendar password (password of team-member who has shared the calendar) when adding via "on the network" method, so I am unable to complete the process. Google Workspace seemingly does not provide an iCal link option when looking at integration settings. 'Google Calendar Provider' has been a common solution I've seen suggested for similar problems, but recent reviews suggest the add-on has broken after the latest Thunderbird update. Any other workarounds for this task? It would be sufficient even to write a script that listens for new events/updates from the shared calendar and re-create them in a Thunderbird calendar, but I haven't gotten into writing add-ons for Thunderbird just yet.
