Could you have option like this (the insert new thing) in menu inside the game for configuration for custom sound?

So I could add the equipment from this info additionaladditions:gilded_netherite_boots it's own unique sound

'Cause I can't really find any sound asset (ogg) inside the folder when I'm uncompress it that I could change, other than .json and .class.
Thank youuu

Oh and, I think it's better if you add hover sound on button of menu.

Adding a configuration screen for whole items seems impractical for this mod only, I would rather have this functionality as a separate tool, not only for ExtraSounds - I'm still working on that tool currently:

It still needs a fair amount of work, but it mostly works already :)

Not only for ExtraSounds but other mod, holy cow that's cool!
