How do you make a "Special" Tool define which enchantments to mimic:

First of all, I am making a 1.12.2 mod of MCreator

So I am trying to create some Weapons with the "Special" Tool option.

I do this, because the "Sword" section doesn't allow people to change attack speed (at least in this version)

I would like to make that my custom weapons use the enchantments of weapons (Sharpness, Fire Aspect, etc.)

Right now, when I enchant my weapons I only get Unbreaking.

Any help?

Thank you for reading.
