Para testar:

* Abrar o aplicativo com várias abas do navegador.
* Escreva mensagens a partir delas.
* Então feche uma das abas.

Isso levantará a exceção `WebSocketDisconnect`, e todos os outros clientes receberão uma mensagem como:

```
Client #1596980209979 left the chat
```

/// tip | Dica

O app acima é um exemplo mínimo e simples para demonstrar como lidar e transmitir mensagens para várias conexões WebSocket.
