Hello!  
Let’s say we want to connect to external WebSocket API using

```auto
val webSocketFlow: Flow[Message, Message, Future[WebSocketUpgradeResponse]] =
      Http().webSocketClientFlow(WebSocketRequest("wss://..."))

val incoming: Sink[Message, Future[Done]] = Sink.foreach[Message] { ... }

val outgoing = Source.maybe[Message]

val (upgradeResponse: Future[WebSocketUpgradeResponse], closed: Future[Done]) =
      outgoing
        .viaMat(webSocketFlow)(Keep.right)
        .toMat(incoming)(Keep.both) 
        .run()

```

Does it possible to stream this data to internal clients (to microservices which providing real-time analytics) using own WS endpoint?  
To make this possible, I need to “connect” `incoming` sink from code above to `msFlow` below, but I have no idea, how to define `msFlow`

```auto
val websocketRoute =
          path("ms") {
            handleWebSocketMessages(msFlow)
          }

val serverBinding: Future[Http.ServerBinding] = Http().bindAndHandle(websocketRoute, $host, $port)

```

What is the right approach to solving this problem at all?

Thanks!
