How can I set broadcaster/key/cluster/enabledTransports parameters?

[anonym24]

So JS has the following implementation and it works:

class MyEcho {
  constructor(token) {
    this.echo = new Echo({
      broadcaster: 'pusher',
      key: process.env.REACT_APP_PUSHER_APP_KEY,
      cluster: process.env.REACT_APP_PUSHER_APP_CLUSTER,
      wsHost: process.env.REACT_APP_SOCKET_HOST,
      wsPort: 6001,
      enabledTransports: ['ws', 'wss'],
      auth: {
        headers: {
          Authorization: `Bearer ${token}`,
        },
      },
      authorizer: (channel) => {
        return {
          authorize: (socketId, callback) => {
            const data = {
              socket_id: socketId,
              channel_name: channel.name,
            };
            window.socketIdMain = socketId;
            api
              .post(WEB_API_ROUTES.auth.broadcastingAuth, data)
              .then((response) => {
                callback(null, response.data);
              })
              .catch((error) => {
                callback(error);
              });
          },
        };
      },
      forceTLS: false,
      encrypted: true,
      disableStats: true,
    });
  }

For Android I could only set host, port and token:

    val options = EchoOptions().apply {
        host = SERVER_URL // for example: "https://socket.example.com:6001"
        headers["Authorization"] = "Bearer $token"
        authEndpoint = "/broadcasting/auth"
        //eventNamespace = "App.Events" // not sure what is that, does it equal "broadcaster" of JS library?
    }

    echo = Echo(options).also {
        it.connect(
            { args ->
                Timber.d("ChatSocket successful connected: ${args.joinToString(", ")}")
                listenForEvents()
            },
            { args ->
                Timber.d("ChatSocket error while connecting: ${args.joinToString(", ")}")
            }
        )
    }

How can I configure all other parameters - broadcaster/key/cluster/enabledTransports?

Right now I can the error on connect ChatSocket error while connecting: io.socket.engineio.client.EngineIOException: xhr poll error
