How to use the @azure/amqp-common.ConnectionConfig.validate function in @azure/amqp-common

static createFromConnectionString(
    connectionString: string,
    options?: ServiceBusClientOptions
  ): ServiceBusClient {
    const config = ConnectionConfig.create(connectionString);

    config.webSocket = options && options.webSocket;
    config.webSocketEndpointPath = "$servicebus/websocket";
    config.webSocketConstructorOptions = options && options.webSocketConstructorOptions;

    ConnectionConfig.validate(config);
    const tokenProvider = new SasTokenProvider(
      config.endpoint,
      config.sharedAccessKeyName,
      config.sharedAccessKey
    );
    return new ServiceBusClient(config, tokenProvider, options);
  }
