Please provide more information on your requirements, do you just need to set up the webcam to ensure the webcam is positioned... etc. correctly before the remote session?
If so, if you open the built in Camera app in Windows 10, are you able to use that to test the webcam is working correctly before the remote session is started?
If that is not what you need to do, please provide some more information on your requirements and also, what app are you using for the remote session.
