Two monitors with different views during "hybrid" meeting

Smart people:

We often have "hybrid meetings", meaning people in the conference room plus people on Zoom.   Our conference room setup involves a laptop dedicated to managing the Zoom meeting with a large (72") monitor on the wall and an Owl camera for video and audio.    Works well, as far as it goes.

We'd like to add a second monitor (and controlling laptop if needed) so that we can ALWAYS see the gallery.  We often switch to a shared desktop view and folks in 'Net land get torqued off because we can't see all of them as they raise their hands with questions.

So, ideal situation: one monitor displaying the current speaker/desktop/whatever and one monitor showing nothing but a gallery view no matter what other foolishness is going on.

How do we get there?

Thanks in advance!
