// <client-access-uri> is copied from Azure portal mentioned above.
var client = new WebPubSubClient(new Uri("<client-access-uri>"));

// ...code from the last step

// Provide callback to the "group-message" event. 
client.on("group-message", (e) => {
  console.log(`Received message: ${e.message.data}`);
});

// Before joining group, you must invoke start() on the client object.
client.start();

// Join a group named "group1" to subscribe message from this group.
// Note that this client has the permission to join "group1", 
// which was configured on Azure portal in the step of generating "Client Access URL".
