Pixelmon Generation Sidemods

hey i need help to set up pixelmon generations without using the technic pack

i am trying to add pixelextras which is a sidemod for the generations version but i dont know how, also i dont want to use the technic pack because you cant use any plugins with it and i need the luckperms plugin for my server so my players can use /pokeheal etc.

also here are the side mods for generations, i cant find them in the server hosting website.
