[NEED HELP PLEASE] Trying to make a compatibility patch between a modded class and another mod on Baldur's Gate 3

[Orjan08]

Hi, I've been working on a compatibility mod to no avail for the past week. The goal is to make Spellsword Class (formerly Vanguard, from Gawesome) compatible with Extra attack at character level 5 by bigmax, a mod found in the in-game manager. Since I don't know the first thing about modding and have just put my hands in it to translate Spellsword Class to French, I've been using AI, first Copilot, then ChatGPT, to help me in these endeavours. It eventually worked out for the translation, but not for the compatibility patch, at least yet. Would there be any knowledgeable person who'd be so kind as to help the massive noob that I am? I'm sure it's trivial but for me, it's exceedingly complicated. Thanks in advance!
