CraftTweaker Integration 1.15.2

[SlamWeasel]

Could you help me with your CraftTweaker Integration?
Im not sure what to import to change recepies. All Im trying to do is add recepies in the Chopper and Sawmill for logs added by other mods, since you can simply go around the whole starting process with that.
There is a description how to use it for the 1.12 version, but Im using the 1.15 verison, and havent found anything on how to use it
Thanks
