What's the instance name of game.view.properties/explorer/output?

I’m thinking of making a Plugin that lets me instantly turn off/on Explorer, Output, and Properties at the same time by clicking a single button on the screen. Those things you use on Roblox Studio to do stuff.

The problem is that I don’t know where to find it, nor where to look for it. Because I don’t know what it’s called.

Edit: By making something like that, I can quickly see what my GUI’s will look like when I’m playing the game on pc. Otherwise I’d have to play the game, then manually turn off Properties, Explorer, and Output to get the full 1920x1080p something ViewportSize to see how my GUI’s scale.
