On-Camera Timer

As the host of a meeting, I have a need to track the time that an individual has their camera switched on.  In the participants pane, it shows when a participant is muted, when they have their camera on, when they are screen sharing, etc. However, it is displayed as an icon.  I need a report of how long the person had their camera on (or off) for the entire session.  The reason for this comes down to compliance.  Being on-camera is mandatory for the meetings I host.  Tracking in the main session is not too difficult.  However, when the participants go to breakout rooms, it is much more difficult to track.  A field added to the Active Hosts > Participants report would do the trick.  Or, if there are any plugins that can track on-camera time for each participant, that would be grand.
