Need Help With 3D Escape Menu Button

[Revenance]

Basically I have a Scriptfodder addon called 3D Escape. To look at pictures or view the script, [URL="https://scriptfodder.com/scripts/view/1659/3d-escape-menu"]click here[/URL]. Anyways, there are buttons you can click like website, forums, disconnect, and even close the escape menu and go back to playing. Well, I want to add a button so when you click it, it takes you to the main menu. I will leave a small amount of the script below for it to be able to be solved and not be considered a leak. Someone please help i'm lonely and desperate. (P.S. I would ask the creator to help me but he isn't answering any of my tickets so yeah.) I also added some things like GM:MenuStart() because I was trying to fiddle around and make it work, but it obviously didn't.

MENU:AddPanel( b )

local b = Button:New()
b:SetHeight( 48 )
b:SetText( "Main Menu" )

function b:Clicked()
	surface.PlaySound( "garrysmod/ui_click.wav" )
	GM:MenuStart()
end
