Describe the feature you'd like

CraftTweaker supports GregTech Community Edition (the vanilla one, let's say) but does not support the new continuation of it, GregTech Community Edition: Unofficial.
I'm particularly interested in adding lossless cables (taken from Omnifactory), but this doesn't work as CraftTweaker fails to register the new cables.

CraftTweaker itself does not support Gregtech at all, it is all added by GregTech themselves.

Both of those mods have CraftTweaker related code in their repositories:
https://github.com/GregTechCE/GregTech/tree/master/src/main/java/gregtech/api/recipes/crafttweaker
https://github.com/GregTechCEu/GregTech/tree/master/src/main/java/gregtech/api/recipes/crafttweaker
