如何在C#中的谷歌OAuth中添加配置文件范围和电子邮件范围(Windows form)

using Google.Apis.Auth.OAuth2;
using Google.Apis.Oauth2.v2;
using Google.Apis.Oauth2.v2.Data;
using Google.Apis.Services;

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
    ClientSecrets = new ClientSecrets
    {
        ClientId = "YOUR_CLIENT_ID",
        ClientSecret = "YOUR_CLIENT_SECRET"
    },
    Scopes = new[] { Oauth2Service.Scope.UserinfoProfile, Oauth2Service.Scope.UserinfoEmail },
    DataStore = new FileDataStore("Store")
});

AuthorizationCodeRequestUrl url = flow.CreateAuthorizationCodeRequest("YOUR_REDIRECT_URI");
url.AccessType = "offline";

webBrowser1.Navigate(url.Build());

private async void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
    if (e.Url.ToString().StartsWith("YOUR_REDIRECT_URI"))
    {
        string code = e.Url.Query.Split('=')[1];
        TokenResponse token = await flow.ExchangeCodeForTokenAsync("", code, "YOUR_REDIRECT_URI", CancellationToken.None);
        // 使用访问令牌进行后续操作
    }
}
