Removing My Circular Image from my Virtual Background, and still appearing against it

I've installed Zoom on my Chromebook (android).

I want to remove my circular image (which shows parts of the room I'm in) from my virtual background,

but still appear against the virtual background as if I'm actually in that world.

I can shrink the circular image, but then I can't be seen against the virtual background.

Anyone know how to eliminate the circular image, and still appear against the virtual background?

I can do this on my desktop, but not on my laptop.
