One participant in the zoom

[Mikhail2]

We have pay-per-view zoom (Zoom Meetings Education). Students listen to lectures either off-line or on-line. We record the lecture in zoom. If all students come to the lecture and there are no students on-line in zoom (only the teacher is in zoom), then zoom switches itself off after some time and recording stops. How can I make zoom not switch off even if there is only one participant in it?
