EventBridge rule silent on `genesyscloud:conversation:created` pattern match

Dashboard aggregator expects the stream but the rule stays dead. Event pattern matches the docs for detail-type: "Conversation Created" yet the target Lambda doesn’t invoke. Pattern JSON below.

{
 "source": ["genesys.cloud"],
 "detail-type": ["Conversation Created"],
 "detail": { "routing": { "queueId": ["*"] } }
}

CloudWatch logs show zero matches. Tried broadening detail to * still nothing. Token refresh works fine. Checking detail structure again.
