[Help] Need help with figuring out custom eup

hi! I’m doing eup for a british server and i’m using these two resources.

(ik they’re not on the same version but with the outfits I have it shouldn’t matter)

I’ve renamed and done everything like that correctly. Now I just need to figure out how to add these outfits to eup-ui (or if there’s any other menu), I couldn’t seem to find a tutorial anywhere. And I don’t want to use vMenu for these resources because it’s an esx server.
Any help would be appreciated,
