new and confused about making datapacks for mods specifically

hai I recently started getting into making datapacks, since it was more approachable than making full on mods and this feels like a good first step into this typa thing XD anyways, long story short, I've been trying add recipies to this modpack ive been playing and it's not working at all. All the recipies Ive added are for create's "crushing wheel" first I tried crushing an item from mysical world, didnt work. thought it was maybe bc it had a similar tag to a blacklisted item or smth and mystical world wasnt origionally in the pack. then I tried crushing an item from tinker's construct, didnt work then I was wondering if it was bc I was missing something that connects the mods in the pack somehow, so I tried crushing a vanilla item and that didnt work so i have no idea what im missing.. (im in 1.18.2 btw) I went down this whole rabbit hole about what the hell a "schema" is bc visual studio kept giving me a warning that the schema it automatically put wasnt gonna be right in some way and turned them off bc thats the only warning I was getting on the code but it didnt solve the issue and now I just have no idea, are schemas required or smth??
