How to edit world array in Scene manager?

Godot Version

4.4 (plugin is 3.2)

Question

This is the first game I’m working on so I’m lost with a lot of things. I’m using the “Level Manager” addon from the official godot asset library. In the readme…

"Attach level_manager.gd to the root node of a(n ideally empty) scene in your game and set it to the "Main Scene" in Project Settings -> General -> Run if not already
Resize the world array to fit the PackedScenes you'd like to use in the game
Add any PackedScenes you'd like to instance in the game
Set the curr_scene to the index of the scene you'd like to be loaded at the start of the game"

I’m pretty sure I understand what its saying to do, just I have no idea at all where it is. Searched for world array in all the scripts that came with the plugin to no avail. I need to put the scenes(levels) of my game into the list. Where is the list? Where do I resize the world array? I’m assuming I’m missing something super basic. Also I don’t know how is the best way to show the scripts I’m working with.

export (Array, PackedScene) var world
Line number 3 of the file level_manager.gd.

However !!! This is an old manager designed for Godot 3.x and will not work with Godot 4.x
You should abandon this level manager at least until you have a much better understanding of Godot/GDScript. At that point you may be able to convert it to 4.x ready code but by then you may just roll your own.

So I made a very dumb mistake and was looking at the wrong addon. That would explain why I was going insane trying to look for it. I do need to just figure it out and do it myself thanks.
