Why not just a share a new virtual desktop and move windows to it that you want to share?
I do a lot of live demos for customers, and I kept being nervous about what else was on my screen: notifications, other clients' windows, a messy desktop. Sharing one window is safer but then I'll be stuck with one window. So I built Sel.
First, pick the windows you want to show. Then, they'll be captured via ScreenCaptureKit and composited on a Metal pipeline into one canvas, over a background, and with an optional webcam bubble (and other kinds of overlays). You share that single canvas window in Zoom/Meet/whatever. The rest of the desktop never enters the frame, and you can prepare named "scenes" (demo, code, browser, etc) before the call and switch between them live, with a transition.
