Invalid Fullscreen ADB command is not working

[SnN Day :)]

Hi, I've noticed some slight retention on navigation bar and so before it's too late I've been searching for an ADB command for Fullscreen Immersive mode without Root. That was perfect for me.

THE COMMAND:
adb shell settings put global policy_control immersive.full=*

That doesn't work for me for some reason :/
Still steady, doesn't disappear in any app except for full screen YouTube (it's already been set so no difference)

The phone: Xiaomi Mi 11 Ultra
MIUI 14 version: 14.0.2
Bootloader: Unlocked (no root)

I realized that Google removed this feature from Android 11 and above
Magisk ftw

It is working perfectly on my Android 14 Samsung tablet but not on my android 14 Poco so maybe it's not Google but Xiaomi? It would be really nice if we could perform the above mentioned adb command.

Running ADB commands is not something the average end-user should be doing. This isn't part of MIUI/HyperOS and has no place in our Bugs subforum.
