    "slack_client": sc
    else yields {"message_data": m_data} and the caller can handle that
    When encountering an error (e.g. invalid message), yields {}, the caller can proceed to the next message
    When the websocket being read from has given up all its messages, yields {"done": True} to
    indicate that the caller has read all of the relevent data for now, and should continue
    its own processing and check back for more data later.
    This relies on the caller sleeping between checks, otherwise this could flood'
