I'm in a Zoom meeting tomorrow - not as an administrator - and will explore solutions. You are not alone in your problem. I have a friend who administrates Zoom meetings who has trouble keeping track of 10 people. Apparently it is even worse on a phone.

Many very low tech ways to skin cats.

Many years ago you might remember there was a spate of trying to stop people right clicking on things. Which worked unless you knew that if you left clicked on them and kept the left click down you could then right click...

Where I used to work there was a software problem that meant that a certain number of images were missing on a very major website (estate agency/houses for sale). Management answer was that x% of images missing was "acceptable". What that related to was HUGE numbers of calls on a bad day and quite a number of calls on a good day.
