in Remote Desktop Support option, is there a way to access that other person's Zoom options?

I often host Zoom meetings with attendees where the attendees are not tech-savvy at all. They can click and join a Zoom link but that's about it. Sometimes the attendees's microphone options are not set right (too low, for example). With the attendees permission/approval, I want to be able to adjust their Zoom microphone options.

I have tried using the "Support --> Request desktop control" of that person's computer (with their permission/approval). When they have given approval for me to do Desktop Support, the Desktop of their computer appears, but I can't access the Zoom client itself. I tried clicking on the Zoom client at the bottom of the screen but it does not bring up the Zoom client itself.

anyone know if this is even possible, to be able to access the Zoom client to modify the microphone setting (increasing input level), even while the Zoom meeting is running?
