Oops, I mean 1.20 💀. I'm used to play on 1.12 too much lol

I'm not updating the mod for 1.20 since Mojang optimized DFU load times significantly enough that this mod likely won't make a dent except for the very lowest-end systems. Until I see credible evidence otherwise, an update is unlikely.

You're free to try the latest build and see if it works. I don't think the relevant logic has changed all that much.
