How do I make items shoot custom projectiles in MCreator 2023.2?

I need to make Dragon Breaths, but all I can shoot is a few fireballs, 2 arrows, or 5 throwables. Can I somehow add an item to these lists? I need to make a custom projectile that spawns a custom fire when it lands, a projectile that spawns a water trap around the player/entity it hits, and one that spawns a suffocation trap at the player/entity it hits.

Thx in advance
