Change LoadLibrary to what?

In my script, it says that load library is deprecated.

function CreateWarning(Player)
	local RbxGui = assert(LoadLibrary("RbxGui"))
	local Screen = Instance.new("ScreenGui")
	Screen.Name = "NotInGroupGui"
	local Gui = RbxGui.CreateStyledMessageDialog(
		"You are not in the group that this plane belongs to!",
		Player.Name..", you are not a member of the group! Please exit the plane!",
		"Confirm",

It would be really nice if someone could fix this. Thank you for your time.
