get all meeting attendance reports in a group or channel

Hello developers, I'm currently working on a project that requires to extract all meeting attendance records from teams and I found that using Graph API can only get access to a limited number of records. This is my method using the graph api to extract the attendance records.

1. get the list of groups and their group ids under the user.
   'https://graph.microsoft.com/v1.0/me/joinedTeams'
2. listing all the events for each group and find the meeting id for each event
   https://graph.microsoft.com/beta/groups/{group_id}/events
3. for each event, find the attendance records
   https://graph.microsoft.com/beta/me/onlineMeetings/{meeting_id}/attendanceReports
4. get the attendance record for each meeting
   https://graph.microsoft.com/beta/me/onlineMeetings/{meeting_id}/attendanceReports/{record_id}?$expand=attendanceRecords but this method only gets the attendance records for those meetings scheduled in the Calendar before hand, is there any other way to extract all meeting attendance records for each group using graph api? Thanks
