Calendar subscription
Your calendar app can show all plans you host or responded to in this browser. It updates them by itself when a plan changes, is cancelled or deleted.
The calendar has only public details: title, time, meeting area and the link. Never the exact start, the route or anyone’s name. Your calendar app’s server fetches it, so that server sees these details and that you responded.
Create a plan or respond to one in this browser first. The calendar link lists those plans.
