Adjusting size of presenter when viewing webinar

[samcleve01]

I'm posting from the POV of a webinar attendee, not as a host/planner. I am using Zoom Workplace version 6.4.0 on Mac Ventura. I swear there used to be a way for me, as an attendee, to adjust the size of the presenter's camera view while they are sharing their screen.  For example, you could have the presenter and their PowerPoint side-by-side, and drag to adjust the size of the presenter  relative to the size of their PowerPoint slide. Now all I see is the option to switch between the slide and a camera view up top that is so tiny you can barely make out the presenter's face. If you switch, then the shared PowerPoint is way too small.

I realize that if you go full screen, you gain some control, but this is awkward compared to the side-by-side view, requiring multiple clicks rather than just dragging to adjust. I swear I looked through all of the view settings and can't see a way to switch to a view that makes the presentation engaging -- in other words, you can clearly see the slides, and their face, side by side, at the same time.

I don't see an option to share a screenshot, so here's a link to a (heavily-redacted) one:

Thank you.
