We recommend that you schedule meetings in room resource calendars. Room resource calendars, unlike regular user calendars, offer the following benefits:
Automatic event approval or rejection
Scheduling conflict management
User-friendly room booking interface
Assigning users as resource delegates
Working time settings
Management of each Google Workspace user’s permissions
E.g. Free/Busy items visibility
Private event settings
To integrate Google Room Calendars and MeetingRoomApp with Service account key, you will need the following:

Impersonation user (service account email, e.g. meetingroomapp@domain.com), the service account needs to have access to the room resource calendars with the "Make changes to events" permissions
To copy the list of calendars, you need to subscribe to the resources at Google Calendar App.
