Describe the bug

I am trying to pass previous text chat conversations as context to the agent and found on the docs only useDataChannel as the way to do pass context but it is not working.

Is this the intended use of the hook? is there another way to pass context or previous messages to voice agent?

Reproduction

ref usage:

  const { send } = useDataChannel("chat", (msg) => { console.log(">> msg sent", msg);
  });
  useEffect(() => {
    if (isAgentConnected) {
      send(new TextEncoder().encode("my name is rodrigo"), {
        // destinationIdentities: ["agent"],
      });
    }
  }, [isAgentConnected]);

the easiest way to send chat messages to the agent is to use the send method of the useChat hook!
