Three flags change the enchantment discovery:

treasure determines whether you can find the enchantment in the enchanting table.
trades determines whether you can find the enchantment as a villager trade.
discovery determines whether you can find it in the enchanting table and in loots. However, treasure takes precedence.

For example, if you wanted it to behave like Vanilla Mending, you'd enable all three flags. This way it wouldn't be found in the enchanting table (treasure flag takes precedence), but you could still find it in loots and trades.
