How to use proxy in ReactPHP?

Question

proxy

There is a problem, I use reactPHP to parse the site, but it became necessary to use a proxy server, in case of blocking, how to do this?
I'm trying to use this lib https://github.com/clue/reactphp-socks
Example:

$proxy = new SocksClient('89.32.68.50:3128', new Connector($loop));
$connector = new Connector($loop, array(
    'tcp' => $proxy,
    'dns' => false
));
$browser = new Browser($loop, $connector);
$browser->get('http://yandex.ru')->then(function (ResponseInterface $response) {
    echo Psr7\str($response);
}, function ($event){
    echo (string)$event;
});

Through curl, everything works fine.
