Hi All,
Can you explain associationProperty and keyName in @SagaEventHandler. How these works

@SagaEventHandler(associationProperty = "orderId",keyName = "identifier")

Thanks,

did you check the reference guide? Specifically this section: https://docs.axonframework.org/part-ii-domain-logic/sagas#event-handling

Cheers,
