How to use a network stream camera

[egel]

I setup a raspberry Pi camera that has a camera. I can stream a live video within the network by entering web address: http://192.168.1.139:8081 in a browser, e.g., google chrome or safari.

I want to make use this streaming in Zoom. So instead of setting Zoom video to a video device, I want to set Zoom video to a streaming address. How do I do this?
