Camera not visible in Azure Virtual Desktop environment.

Hello, 

I am having an issue with using Teams on a VDI Azure Virtual Desktop environment. We have installed the latest version of the Zoom VDI Client on the host, and the AVD plugin on the computer we are using to connect. After connecting we test Zoom, and the camera is still not working. Gray screen, and this is with 3 different usb webcams. The same webcams work fine within teams and the default camera app. They also work fine with zoom on the physical machine, just not within the virtual environment. Any guidance would be greatly appreciated.
