Crosshair (mouse.Icon) not working?

I've uploaded a custom crosshair, and it doesn't appear for me

Crosshair: It's uncopylocked as well, and it's my upload

My code:

wait()

workspace.CurrentCamera.FieldOfView = 100

local mouse = game.Players.LocalPlayer:GetMouse()
mouse.Icon = "rbxassetid://5466135695"

I don't get any errors in console
