You have to use Microsoft's OOB experience. Improved with "handheld mode", but still not as slick and you are not allowed to improve it.
You can have a "full screen launcher", but you have to boot to Explorer and then run your Big Picture Mode.
Steam do on Windows through "Big Picture" mode.
Absolutely. The UI on Windows 11 is not designed for couch gaming, and Microsoft licencing rules mean that you are not allowed to hide Windows.
