How to make custom mouse icon go away?

I used to use Mouse.Icon = nil to make it go back to normal but it seems like that doesnt work anymore. Does anyone know how to set it back to the default cursor??

I believe you have to set it to an empty string.

Can you paste the part that changes the custom cursor icon please?
Edit: if you wanna make the default icon visible again you can do

local UIS = game:GetService("UserInputService")
UIS.MouseIconEnabled = true -- false if you wanna make it invisible again.

Make an event make it go away, like clicked or touched or wait, etc

game.Workspace.Part.ClickDetector.MouseClick:Connect(function(hit)
script:Destroy()
end)

this is a second task you could add in the same script that sets the mouse icon

Simply set the cursor back by using the cursor in the default Roblox files.

I do believe you could also set it to an empty string but I have never used that method.
