More control on Guest Mode or Access Guide

Hello, I have a use case for the Apple Vision Pro glasses as follows: I want to allow others to use the glasses, but only for a SINGLE app and to be able to use the physical buttons. I have tried the following methods:

1. Using Access Guide: This method meets most of my needs, but I cannot use the two physical buttons to take a screenshot.
2. Using Guest Mode: This method meets most of my needs, but there is a session issue. Each session ends when the glasses are removed -> I want the session to end in a more controlled manner.
3. Using Screen Time: This method can limit many things but cannot prevent users from returning to the home screen.

I would like to ask if there is any way that can be applied to my case. Thank you very much!
