as @_omgasaid, its outdated and most likely will not be added.
BUT, you can use:
Skript
CraftEnhance
Both plugins there allow you to make custom crafting recipes.
you can always host a minecraft server on your own pc and have any plugins you want on it without having to request them or anything. there's multiple videos on how to host a server from your pc for personal use. (i wont link any because Idk if ill get in trouble or not.)
I'm pretty sure when a plugin is red in /plugins it means its outdated/not going to work.
dont quote me though, I just know if their red they wont work lol
