Ymap on fivem m

hello, i trying to instal my first mapping that i made with CodeWalker (.ymap). i follow de instruction on the mods description (https://fr.gta5-mods.com/maps/prison-block-ymap-fivem).
i already instal hole fix so ymap can be load. but if i make my own folder (loaded in .cfg off course) it doesn’t load my ymap. if anyone have the solution or a tutorial i would appreciate.

im trying to do this to a ymap and i need help trying to get one to work or how to install it correctly
