OP bought a camera not sold as a webcam and is trying to use it as a webcam. Fair enough, I've done the same.

A standard way of doing that is to use a video cable to get video output and plug that into a capture card on your computer. OP doesn't want to do that and would prefer that the manufacturer included webcam functionality out of the box.

Also fair enough! But if that's the requirement, buy a camera that meets that requirement, and understand that it's not a standard feature in these cameras.

I get subscription fatigue, but this is not a good hill to die on. It's getting outraged over expecting a camera to do what it wasn't designed to do, when there are already simple and standard ways of making it do that.
