Hi.
Thank you for posting the question to Microsoft Q&A forum.
According to https://learn.microsoft.com/en-us/windows/configuration/lock-down-windows-10-to-specific-apps
Currently, multi-app kiosk is only supported on Windows 10. It's not supported on Windows 11.
I suggest that you could submit your requirement in Windows 11 Feedback Hub (win + F).
Best regards,
