'Share screen' (like Zoom) as a cue background option

Using 'Presenter' with Zoom for online services works really well. I've often thought it would be great to be able to select the zoom app as a background so you could still the musician/speaker (on Zoom) while over laying lyrics/scripture/text slides etc..

How it would work:
I 'share screen' from Zoom clicking on my second screen which shows the 'Presenter' output display. A cue is set up in Presenter which has the Zoom App selected as the background meaning you still the person speaking on Zoom. The foreground is then set to show lyrics; scripture.....
This would be a game changer for current online use...

Could you go over the steps to include a Zoom call within Presenter? Thanks!
