I realise that this is well after the event but trying this did not work for me. Tw sets of code below both of which result in an error - 'the requested entity was not found'. This is odd because if I change "remove" to "create", the function succeeds.

  function removeStudents() {
  //Classroom.Courses.Students.remove({
  // userId: "[email protected]",
  //}, 727305413955);


var ClassroomID=727305413955
var TeacherslistID="[email protected]";
Classroom.Courses.Teachers.remove({"userId":TeacherslistID},ClassroomID)
}

The error lists this line as at fault Classroom.Courses.Students.remove

Any update on this would be appreciated.
