How do I make tools/armor from my mod compatible with Reskillable?

(I'm modding for 1.12.2 using MCreator 2021.1 if it helps)

I'm planning on making a mod compatible with RLCraft, and added a few pieces of armor, how would I make it so that players cannot use certain pieces of armor/tools unless they have a specific skill level (using the Reskillable mod)?

Thanks in advance for any help! :)

(Edit 1: I found that in reskillable's config, you can make certain items required for skills, but I'm still unsure how to set config via another mod?)
