Turning Off Center Stage

This is a tip, not a question.

A few people have asked how to turn off 'Center Stage', the feature that tracks you on your Mac's camera, which affects, Photo Booth, FaceTime and Zoom…maybe others.

Apple's instructions are "macOS Ventura 13 or macOS Monterey 12: Click Control Center in the menu bar, click Video Effects, then click Center Stage." Use Center Stage to keep you centered in the camera frame - Apple Support

…but it's not there. 'Center Stage' is not in Settings, either.

…which I applied to FaceTime (open FaceTime and click the top-right menu to reveal the Center Stage on/off button).

This worked and turned it off Photo Booth, too. So it looks like a *general* control, not an app-specific control. Therefore, it should surely be in Settings, not in a particular app 🤷‍♀️
