Paused screen-sharing for background full-screen Google Slides presentation

[floatyboat]

My goal is to be able to (1) present from Google Slides, (2) while seeing the presenter notes, (3) while the audience sees the full-screen presentation, and (4) all from a single display. This seems impossible with Zoom which is ridiculous. 

Here's my process for testing this:

1. Start Zoom and create test meeting.

2. Open my Google Slides presentation in Chrome.

3. Invoke presentation mode with presenter notes. Presenter notes open in a second window.

4. I need to full-screen the presentation again because presenter notes in Google Slides minimises the window slightly.

5. I tell Zoom to share the full-screen presentation.

6. I put the full-screen presentation in the background (not displayed on my single physical display).

7. I pull up my presenter notes, only to find the Zoom pauses my screen-sharing because the presentation is in the background, even though I've clearly selected that window in sharing options.

There seems to be no solution to this using Google Slides, unfortunately, but I'm hoping someone has worked out what the trick is.

This works perfectly well on using PowerPoint which I could use but I shouldn't need to have PowerPoint to achieve this very simple outcome.

There are some horrible workarounds, like side-by-side windows on my single display but the audience sees the browser and the presentation is not entirely full-screen (ugly and unprofessional). I am not interested in workarounds. 

Fingers crossed.
