[C#]Составить запрос к ютубу

Нужна помощь в создании такого запроса к ютубу

Все данные для запроса есть, осталось только составить его, отправить и получить ответ. Есть такой набросок запроса, только без передачи параметров, также есть одна загвоздка, заключается она в том, что если раскрывать context, то там ещё миллион миллиардов каких-то параметров.

        string mail = "";
        string apiKey = "токен";
        HttpWebRequest requ = (HttpWebRequest)WebRequest.Create($"https://www.youtube.com/youtubei/v1/channel/reveal_business_email?key={apiKey}8&prettyPrint=false");
        requ.Headers.Add("сюда параметры: id канала, а потом капча");
        HttpWebResponse respa = (HttpWebResponse)request.GetResponse();
        using (var reader1 = new System.IO.StreamReader(responsa.GetResponseStream(), encoding))
        {
            mail = reader1.ReadToEnd();
            reader1.Close();
        }
        
        Console.WriteLine(mail);

параметры строки запроса: key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8&prettyPrint=false
