Can a notes app float content via AVSampleBufferDisplayLayer PiP, or will it get rejected?

Hey,

I’m working on a notes app and thinking about letting people keep a note visible with Picture-in-Picture while they use other apps. For example, floating a todo list while shopping with Safari or scrolling socials...

It would only start if they tap something like “Float Note”, never automatic. They can stop it anytime.

Would be using the usual public PiP APIs (AVPictureInPictureController + AVSampleBufferDisplayLayer), similar to some existing note/PiP apps already on the Store.

Would App Review be okay with that as an optional, user-started feature in a notes app?

Thanks.
