	permission: op
	trigger:

		set {_gui} to a new chest inventory with 6 row named "HAHAHAHA"

Skript: spawncommand.sk

command /spawn:
	trigger:
		teleport sender to world "[INSERT YOUR WORLD NAME HERE]"'s spawn

Delete the brackets and the message, and then put your world name inside

I'm also not sure if you need SkQuery for this
