ItemJoin v5.2.2
Hello. How do I disable players throwing the EXP Bottles? Thx

I apologize for the late reply, I have been experiencing power outages due to a windstorm.
The itemflag cancel-events should work for this as it is similar to ender pearls.

Example;

  exp-item:
    id: EXPERIENCE_BOTTLE
    itemflags: cancel-events
    triggers: join
    enabled-worlds: ALL
