[nanaann]

I am Dell tester, according to the tickets: https://support.zoom.us/hc/en-us/articles/202952568-My-Video-Camera-Isn-t-Working there is a notification when we have zoom video call while SUT's camera on, but we cannot see the notification while the native camera is launched at the same, can see the notification if the camera is external camera. OS version: 19042.2364, ZOOM version: 5.11.7185. Can you help please solve my question? Looking forward to receiving your replay soon, thanks a lot.
