How to change mouse cursor?

I've been trying to make a game where the mouse cursor is different. For example, Phantom Forces has a mouse cursor that is different from the default one. I've tried this script but it doesn't work.

ocal mouse = game.Players.LocalPlayer:GetMouse()
mouse.icon = 'rbxassetid://117431028

Some people say use "ImageID" I used a decal How do I get an imageID?

The mouse icon must be expressed in a string so it should be like this:

local Mouse =game.Players.LocalPlayer:GetMouse()
Mouse.Icon = "rbxassetid://117431028"
