How would I get the new Core GUI in studio?

So recently, I was going around Roblox’s Core GUI in-game, and noticed a good looking UI that I want to copy over to one of my games.

For instance, this is the new Core GUI “SettingsSheild”. (Available in-game.)

This is the old Core GUI “SettingsSheild” that is enabled in studio. (That I was able to copy over from theCore Gui Folder)

So, how would I be able to copy over the new core gui to my game, how would I be able to enable the new core gui in studio so I could copy it from the Core Gui folder and get it in my game. (if even possible)?
