Legacy event variant
The same notification also has the legacy eventType sentMessageREAD; the example above shows sentMessageREAD_v2. The legacy base payload does not define localMessageId; do not require it when handling the legacy event. V2 adds caller correlation where available. Other payload fields follow the notification type.
