Most of the time, we forget to record the session. It would be great if there is popup/confirmation asking whether to record the session as soon as the Host/Co-host joins.
If the host clicks Yes , then have the recorder icon appear on the top right corner
If the host clicks No, then no action required
If Yes, have the recorder button/icon with start and stop buttons at the top right corner. So that the host can click the start button when they want to get the recording started.
Even the host clicks No, later they can use the recording option from the menu available which do exist already.
