When considering about the `Request/Response` flow in MQTT5, there's a concept of `Response Information` [1] which can be used as the root of a topic tree for a particular Client. However, as I understood this is set from the MQTT broker rather than from the clients. If my understanding is correct, what is the use of the `setResponseInfo` method? If I am mistaken, can you guide me on the correct way of setting the reponse information using clients?

Thanks in advance.

Start by reading the MqttProperties.setResponseInfo method and the MQTT 5 Response Information section linked in the issue. Clarify whether clients set this value and explain the intended use of the method; done means the question has an authoritative, unambiguous answer.
