Hi Duffy,
You need to run Zoom and the MS Presenter screen on the same monitor (Screen 1), then have the Presentation shown on your second monitor (Screen 2). Then in Zoom you can share your presentation window or the second monitor (Screen 2) with your presentation on it.
I don't have Zoom on this computer, so I used Google Meet to demonstrate. The right screen with the two lines of text is my presentation on my second screen that I am sharing in Meet. The left screen has MS (in presenter mode) and Google Meet running.
