a bit confused following apis, these ?

https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/api/user_findmeetingtimes  https://graph.microsoft.com/beta/me/calendar

the findmeetingtimes api should suit scenario. assigned meeting rooms, can list them inside locationconstraint parameter of request body, assigned attendee email id, can add attendees parameter of request body. response of api return list of meeting time suggestions based on meeting rooms available , attendees available. , the names of rooms available listed on "locations" of every suggestion.

update:

pay attention check permissions inside document using api. firstly, account should work or school account, personal microsoft account not supported. secondly,you need have calendars.read.shared, calendars.readwrite.shared permissions.
