Event list - filter by event type/category

Hi,

Trying to filter on event category via the /api/Event endpoint. This doesn't seem possible at the moment?
I'm able to do this via /api/CsEvent?MeetingType=AGM however I would much rather use the proper API endpoints.
I've tried:
/api/Event?MeetingType=AGM
/api/Event?Type=AGM
/api/Event?EventType=AGM
/api/Event?Category=AGM
/api/Event?EventCategoryId=AGM
/api/Event?EventCategory=AGM

All result in "In the query, <...> is not a known property name."
It would be super handy if there was a list of these "property name"s that worked.

Thank you.
