Implementing Single Instance Pattern with Camunda 8 Kafka Connectors

Hello Camunda folks!

We are working on a solution using Camunda 8 Self-Managed in an event-based architecture.
We are faced with a pattern where the same message can be treated both as an intermediate event and a start event.

This means that if there is an already running process instance, the message should be correlated to it. But if there is no such instance, then a new one should be started. This behavior is described as the single instance pattern here Messages | Camunda 8 Docs.

Our goal is to achieve the same behavior using Camunda’s Kafka connectors.

Could you please suggest a solution for that?
Or at least, is it possible to do this via Kafka connectors?

Best regards,
Nick.
