How to use Pixel 6 as webcam on Android 14?

Many reports in the tech press said that Android 14 would include an option to use Android phones as a webcam when connected to another device over USB. Here it is mentioned on the official Android 14 website Upon installing Android 14 on my Pixel 6, I don't see this option. It's supposed to come up on the USB menu when you plug in the phone. I contacted Google Support as a Google One user, but they were useless as usual - hadn't even heard of the feature. Has anyone gotten this to work?
