Just found out that new meetings will be using Webex instead of Zoom. I mainly use my desktop as it's near all of the necessary things I use for meetings, and I only have a USB Camera. I get a "system does not meet min requirements" error, I assume this is referring to the camera as I have a very robust PC, and even with zoom, I don't have the option to use the "simulated" green screen, but I can select my own background and use a green screen. What is the work around for this? Is there an add on download to "enable" this ability?
