I noticed that the inventoryTick function is not called when the trinket is equipped, could this be changed or could a new function be added like trinketOnTick event? I'd want to run. custom code when the trinket is on and this would make it much easier

Trinkets already have a tick, equip, and deequip method. https://github.com/emilyploszaj/trinkets/blob/main/src/main/java/dev/emi/trinkets/api/Trinket.java
