title: Tracking nicknamed Meets attendance
body: <p>In a Google Education (Classroom) context, we are trying to get (via an API) the attendance for the meets generated by a certain nickname (specifically for the ones generated by the google classroom courses).
  We are able to get Meet statistics using the activities.list but there we have to provide a meet_code and we are not finding the way to get the stats for all of the Meets related to a nickname (or at least, identify all of the meet codes related to this nickname so that we can search afterwards the stats one by one).
  Is there any way to do this?</p>
