External webcam

Hey all, I’m new software tester and I appreciate if anyone could help me with this problem.
I need to check whether external webcam can be tested through automation using Robot with Selenium and python.

Shouldn’t be an issue. What is your problem and and where/how is the webcam connected to ?

my test is: Need to connect few external webcam then use any video conferencing app.

Make a real time video call and switch camera during the call

Repeat the test, by attaching the webcam after the session launch.
