Suggestion

Please add support for Catalouge 1.18.2 mod icons are compatibility with it, if I were to suggest an icon maybe a knowledge book since its the recipe book icon and this is it but better and you could say the mod gives you knowledge1

I've written a guide here: https://www.curseforge.com/minecraft/mc-mods/catalogue/pages/how-to-specify-a-custom-icon

Thanks for the suggestion!
This has been implemented in JEI for all versions on 1.18 and 1.19
