video picture size

Hi

I have changed computers, and now, when I'm in a meeting, I am tiny in the middle of the screen. How do I zoom in so that I am larger, and cover more of my background?

Using original size instead of HD just cuts off the side edges of my background but doesn't zoom in on me.

The computer camera doesn't have the function, but I had hoped that in a meeting, Zoom would.

I have Zoom One Pro.

Thank you.
