Why is the VK API token not received during authorization?

Question

In contact with

Good afternoon, comrades, the following question appeared. I'm trying to figure out the VK API, but I'm stuck at the very beginning of the journey. The code below is supposed to return a token, but instead it returns my application ID. Actually the question is why is that so? I did everything according to this video tutorial www.youtube.com/watch?v=TUnqd7ySdl0

public string VkAuth(string Login, string Pass)
        {
            
            using (var req = new HttpRequest())
            {
                req.UserAgent = Http.ChromeUserAgent();
                CookieDictionary cookies = new CookieDictionary(false);
                req.Cookies = cookies;

                req.Get(String.Format("https://login.vk.com/?act=login&email={0}&pass={1}", Login, Pass));

                String Data = req.Get(String.Format("https://oauth.vk.com/authorize?client_id={0}&scope=offline,group,photos,wall&display=page&response_type=token&redirect_uri=https://oauth.vk.com/blank.html", AppID, Scope)).ToString();
                //req.AllowAutoRedirect = true;

                char[] simbol = {'=','&'};
                string[] strData = req.Response.Address.ToString().Split(simbol);

                Token = strData[1];
                UserID = strData[5];

                return strData[1];
            }
        }
