Slide as Virtual Background: I'm not visible on the recording!

Hi,

I'm sharing my screen in chrome, I share google slides in the browser. Full screen.

I'm "inserting" myself properly, and I can see it works during the presentation, but on the recording, I appear with a white background in a small window, just as if I didn't insert myself onto the slides.

MacOs zoom client, latest Zoom update. 

What's wrong?

Zoom client bug? 

Thanks!
