How to replace LoadLibrary?

I tried searching of LoadLibrary for my intro, but however, none works. How do you replace LoadLibrary when I have this code?

local c = game.Workspace.CurrentCamera
local data = LoadLibrary("RbxUtility").DecodeJSON(script.CutsceneData.Value)
local rs = game:GetService("RunService").RenderStepped

(I'm asking for a Code not a website)
