How can the server distinguish between the client's invocation methods of send_message and send_message_streaming?

[Linux2010]

In the HelloWorld program of the example, both client.send_message(request) and client.send_message_streaming(streaming_request) will execute the HelloWorldAgentExecutor.execute method. So how can we distinguish between these two invocation methods within the execute method? It seems there is no attribute in the current context to identify the difference.

(In fact, the current HelloWorld program does not well demonstrate the characteristics of streaming.) I think if we can distinguish the caller, I can call the agent's invoke method and stream method separately in the execute method.
