How do I change how much a custom enchantment costs to apply in an anvil in 1.21?

Currently trying to edit enchantment datapacks in 1.21 Java edition so that they do not cost any levels to apply to tools and armor in an anvil. We've got multiple enchantment datapacks and I don't want to try and put a bunch of enchants on one item just to be told it's too expensive. I've attached a screenshot of the files for one of the custom enchants. What values do I need to change to keep everything the same except for the cost of applying it?
