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.
