Curlopt_proxy support

Hello
i would like to use the culr codeigniter4 library and set the proxy.

i added this line inside the system/curlRequest.php under the function setCurlOption for my code to work .

Code:

$curl_options[CURLOPT_PROXY] = array_key_exists('proxy', $config) ? $config['proxy'] : '';

please could you add something to handle the curlopt_proxy?

thank you.
