I'm trying to create a flow with a group calendar trigger: when a new event is created in a group (or shared) calendar, then find calendar ID via 'get event v3' (or whatever else that could accomplish this) then create same event in Trello. (or some other end goal.)
There is no way to see group calendars in 'Get event' or 'Get events'. My options are only Birthdays, Calendar, United States Holidays and Custom. I have admin privileges, and still only see these options.
I attempted to get calendar ID from Microsoft Graph, but that ID produces "ID Malformed error." I tested several different calendar IDs from our organisation that graph displayed, but I get the 'ID malformed' error each time.
Ideal solution would be to have all available calendars listed in the 'get event' drop-down, or a better way to get calendar ID that works with Flows.
Online forums have multiple questions on this calendar ID issue.
