Other mods items in procedures.

I'm trying to make a procedure that needs to give the player a certain item from other mod
I don't know how to code so I need help as I was unable to find any tutorial. I know that it might be possible with editing the code of the procedure but I can't make it work.
ANY WAY of giving the player this item will do the job.

Info of the item that might be useful:
Mod Name: "Mr Crayfish Vehicle Mod"
Item name: Large Engine
registry item name: vehicle:iron_large_engine

modid: vehicle
If we need any other info ask me.

The full code of the procedure: (did not implement the item yet.) We need to replace the "GoldenMagnetItem" for the item specified above.

package roleplayplus.procedures;
import roleplayplus.item.MoneyBillItem;
import roleplayplus.item.GoldMagnetItem;
import roleplayplus.RoleplayPlusModElements;
import roleplayplus.RoleplayPlusMod;
import net.minecraftforge.items.ItemHandlerHelper;
import net.minecraft.item.ItemStack;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.entity.Entity;

import java.util.Map;

	}
}

For now I have a workaround using the /give command but this may be useful to learn for the future if the target is not a player.
