how do I use LoadAsset Method to load a GUI into the CoreGui in studio mode?

I want my plugin to not have to be used while in play solo in the studio but also without having the plugin code to have to make the plugin itself

so i'm using : game:GetService("InsertService"):LoadAsset(171822538).Parent = game.Players.Player1.PlayerGui

and I've seen some other plugins code and they do : scr = Instance.new("ScreenGui", game:GetService("CoreGui"))

so would I be able to do :

game:GetService("InsertService"):LoadAsset(171822538).Parent = game:GetService("CoreGui"))?

As you know the CoreGui is hidden, I need more info on why you want to insert a Model in the CoreGui, are you inserting a Frame or ScreenGui into the CoreGui? Sometimes the InsertService makes the instance a model, so you'll need to get the children of the model, and set its parent from what you inserted.
