Put everything in auto and drive in S (check the other settings according to the manual). Then (important) turn the camera on before you connect the USB. When you connect the USB, you get some folders opening up on your screen. Ignore them. Finally, connect to Zoom or whatever you are using.
Also, Webex doesn't work with all software. For me, it works with Zoom and not with Camtasia. I haven't tested Teams, Skype, etc.
