Passing additional values through the offer/stream module

So here is the use case, the stream module uses the "echo" function to handle stt and tts, and the offer (frontend endpoint) used to establish the connection.

is there a way to pass a unique value to the "echo" function (new parameter), so we can use it to fetch data from other sources (database) for memory context AI instead of general responses.

I've tried several methods, but none of them seem to work.

Example:

`def echo(audio, additional_inputs):`

`stream = Stream(
ReplyOnPause(echo),
modality="audio",
mode="send-receive",
additional_inputs=["maybe data will be passed here" (i tried but doesn't work"],
)`

Start by reading the Stream and ReplyOnPause entry points referenced in the example, then trace how the offer establishes the connection and invokes echo. Define the intended path for a per-connection value and verify it with a focused example or test showing that echo receives the value.
