Zoom resizes and moves various windows when I share or stop sharing.

I work with a multi-monitor setup on Windows. I keep the Zoom window with the view of other meeting participants open on a smaller monitor near my webcam so that when I'm looking at them, it appears to them that I'm looking at them. On my big monitor, I often have slides open or something that I'm sharing. When I begin sharing, Zoom tries to be helpful and automatically makes the other Zoom window smaller and also moves it. Sadly, that's not helpful at all. In fact it's quite maddening. It's been like this for years. So each time I begin sharing, I have to move and resize that other window back to what it was. Similarly, when I stop sharing, another round of moving windows back to where they were is lived. Is there a checkbox somewhere in Zoom where I can end this torture?
