I believe you are misunderstanding which is on me I'm not exactly doing a great idea explaining it LOL
the game I'm thinking of making has a ton of potential party members the player can pick and choose between, to the point that the built-in Formation menu would be incredibly cumbersome to use, so I was looking for menus that allow for larger viewable lists of reserve members, which let you pick-and-choose which party members you swap out. My best example as a reference would be FNaF World.
I was asking if this plugin has a menu or really anything like that, as there aren't any pictures or videos on this page that show off how the plugin works.
