How to add DLCs to Games on RenpyPocket or Spark PLEASE HELP

Hii I have both Renpy pocket and spark and I’ve been trying to figure out how to download game DLCs onto it for a while now, whenever I install DLCs (as in, extracting the regular game, adding the dlc file then zipping the whole game up) the game itself works but it doesn’t read or add the DLC? does anyone have any ideas
