How do I add G-Suite calendar

I added calendars to Agenda but it only shows iCloud calendars. I would like to be able to add my work email which is a G-Suite address.

Any suggestions?

Agenda should show any calendars that you can see in the Apple Calendar app. If you can get your work calendars to appear there, Agenda should also see them.

Try going into the Calendar settings, and add your work calendars.

Kind regards,
