We are trying to add an UI interaction to indicate health status of directlineline connection. It seems DL does not provide a disconnected status for subscribing. Is there any event that would fire when DL connection become disconnected?

  this.connectionStatusSubscription = this.botConnection.connectionStatus$.subscribe(
      connectionStatus => {
        var status = '';
        switch (connectionStatus) {
          case ConnectionStatus.Uninitialized:
            status = ChatConnectionStatus.Uninitialized.value;
            break;
          case ConnectionStatus.Connecting:
            status = ChatConnectionStatus.Connecting.value;
            break;
          case ConnectionStatus.Online:
            status = ChatConnectionStatus.Online.value;
            break;
          case ConnectionStatus.ExpiredToken:
            status = ChatConnectionStatus.ExpiredToken.value;
            break;
          case ConnectionStatus.FailedToConnect:
            status = ChatConnectionStatus.FailedToConnect.value;
            break;
          case ConnectionStatus.Ended:
            status = ChatConnectionStatus.Ended.value;
            break;
          default:
            status = ChatConnectionStatus.Unexpected.value;
            break;
        }
        // Dispatch to change directline indicator status shown.
      }
    );
