Making an existing mob be attracted by a custom food

Hi,

I’ve been trying to make an item in my mod, that attracts a vanilla creature when hold in the hand. Unfortunately i didn’t found many ways of doing that since we can’t modify existing mob without coding, i found something in the without-code procedure maker,  that check in a radius if there is an entity with the given tag, but when I put the block that makes the creature find a path to get to the player holding the item and tried to add it to my item procedures when hold, it said missing dependencies. I don’t know why it does that, and it stops me from continuing my mod.

Thanks in advance for the answers ( if there is a solution )
