I know this wasn't the mod, but I tried to change ExtraSounds (ver. 2.3.1 for 1.19.2) mod version from 1.19 to ">=1.20.0" in text editor for easy upgrade if the author leave the mods for months. But I thought this was simple as before but I face a dead end. And I stumble upon your jar file here:

If you could help me to change the dependency from 1.19 to ">=1.20.0" of minecraft it would be really helpful, cause I can't read code.
