Hi Team,  
I use Webhook, on my development and going well. In the new system the event stream is using SignalR. I have no idea about it. I have a sample Java doe, that I want to implement in FlowFuse. Can somebody drive me to the right direction how can I do it?

```auto
String url = "URL";
String token = "ACCESS_TOKEN";
HubConnection hubConnection = HubConnectionBuilder.create(url)
    .withAccessTokenProvider(Single.defer(() -> {
        // Your logic here.
        return Single.just(token);
    }))
    .shouldSkipNegotiate(true)
    .build();
hubConnection.on("ReceiveMessage", (message) -> {
    System.out.println("New Message: " + message);
}, String.class);
//This is a blocking call
hubConnection.start().blockingAwait();

```

I did try it, but the documentation is not too god and I couldn't find out how to add the Access Token to the request.

Is there any way to add authentication to this node? I'm getting the "Error: Unauthorized" error as it needs the bearer authentication.
