Hi,
The Camera should show up in Settings > Bluetooth and Devices > Camera page.
If it shows up there, there might be permissions issue.

Go to Start>Settings>Privacy>Camera. (Click this link to access the Settings directly). Toggle Access to Camera as ON. Also, enable the slider for the apps you want to give access to Teams. It should include your “digital conference” Softwares, so make sure Teams and Zoom have the access.
I am eager to hear back from you to find a solution.
