I tried making a new folder in the mod .jar

/compat/alexsmobs/gongylidia/0,1 and 2.png

But it doesn't work in game. Actually no compats work in game, even the create bars of chocolate.
Is that because I tempered with the .jar ? Do I have to recompile myself with the compats ?

I wanted to add partial Alex's Mobs support and thirst was Taken but I didn't find any help on how to do it.

I don't need to add support for those mods on the fabric version as they are (Neo)Forge exclusives.

Unfortunately, this mod doesn't even have the same file structure as the original fabric mod (at least for 1.20.1).
