This only works on Knox supported devices 🤓

I don't have any device without Knox to test it, Do you?

[VedantKalore]

I have Knox supported device, and actually Aliance Shield X requires Knox on Samsung Galaxy Devices to do its functionality. And see your 1st screenshot it shows green dot in front on Knox that means Knox enabled!

No Vedant, Knox permission isn't necessary, I turned off Knox permission and yet the functions are available. V

Ook but I use with Knox a bit better

No need of Alliance Sheild ig... Any shortcut/activity launcher can do this ig...
