Any information about background replacement in the system video effects?

In the docs it looks like something allows you to set a background replacement image in the Control Center controls (like on a Mac).

However, I can't find any documentation on it, beyond this reference in the Apple docs. https://developer.apple.com/documentation/avfoundation/avcapturedevice/isbackgroundreplacementactive?language=objc

Does anyone have any advice to enable backgrounds in the camera system wide?

the feature is available in macOS Sequoia 15.1.1, accessible from the little menu bar icon which shows whether effects, reactions and so on are turned on. What OS are you running, and where are you looking for the facility?
