Set brightness for using Zoom

A lot of webcams are sold out at the moment. That’s my problem. :wink: So I have to use a cheap webcam for video calls. With this webcam all shines very bright.

How can I adjust the brightness for using in zoom?
I already tried to change the settings with “v4l2-ctl”, obs-studio and other apps. But nothing worked.

If you make a zoom account and sign in you can go to the zoom settings you can change the video brightness settings and stuff. It might be only on the desktop application of zoom but I don’t know.
