Add a goat-horn esque cooldown to a modded item (fabric 1.20.1)

[worthy nimbus]

I tried with the following script to add a long cooldown upon using the supplementaries bomb.

    event.player.addItemCooldown('supplementaries:bomb', 200)
})```

It adds a cooldown but not in the way I want it. It doesn't actually throw the projectile any more, and right clicking holding any random item resets the cooldown. What am I doing wrong?
