How do I use OverrideCoreScripts setting in studio settings?

I just noticed this setting, I don't know if it's new or not. I'm guessing this will let me run corescripts in studio but I have no idea how to use it. Any guides or quick advice/knowledge would be appreciated.

I have some advice you dont use that to override core scrips or not comminly used i dont know why its there but if you want to override something go to starterplayer starterplayerscrips localscript an put this code in to disable backpack core script use other things to override different things

game.StarterGui:SetCoreGuiEnabled("Backpack",false)
