Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Adding Custom Map to GM Scenes

So I created a custom map I would like to use as one of the Scenes in GM mode but I can't figure out how to do it. Publishing doesn't seem to do anything, and I can't find the folder where the normal Scene maps are located. Anyone know how to use custom maps in GM mode?
