Great idea, but I couldn't get it installed (and I develop software). The documentation is missing a step. After you install it, click the icon with 9 dots and select Discover Google Workspace, Your Apps and click the app icon. Then I went to pay and it got stuck in processing. Fix your payment connection. :(

Works great and as expected! It syncs two google calendars and makes me busy on the other and vice versa. You have to install this and head to the icon with 9 dots next to your name in the top right corner to get this setup.
