I am trying to use Google Drive API in my Asp.net web app.
I have hosted my on my local ISS and I had deleted the default web site from ISS and put my app in it.
So that I can use the URL "http://localhost"

I am trying to call this method, when I am running it, I am not getting any error the code runs but nothing happens not Consent Screen opens up for permission.

Not sure why this is not working.

public static async Task<bool> AuthenicateWithGoogle()
        {
            ClientSecrets secrets;

            using (var stream = new System.IO.FileStream(CommonFunction.GetFullPath("client_secrets.json",true),
               System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {
                secrets = GoogleClientSecrets.Load(stream).Secrets;
            }

            IDataStore credentialPersistanceStore = getPersistentCredentialStore();
            
            //UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(secrets,
            //        SCOPES, getUserId(), CancellationToken.None, credentialPersistanceStore).Result;

            TokenResponse token;

            token = await credentialPersistanceStore.GetAsync<TokenResponse>("465464").ConfigureAwait(false);
            

            //var credential = new UserCredential(new GoogleAuthorizationCodeFlow(
            //    new GoogleAuthorizationCodeFlow.Initializer
            //    {
            //        ClientSecrets = secrets
            //    }),
            //    getUserId(), token);


            IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
            {
                ClientSecrets = secrets,
                Scopes = new[] { DriveService.Scope.Drive },
                DataStore = new FileDataStore(CommonFunction.GetFullPathForGoogleDataStoreFolder(), true)
            });


            UserCredential credential = new UserCredential(flow, getUserId(), token);


            googleService = new DriveService(new BaseClientService.Initializer
            {
                HttpClientInitializer = credential,
                ApplicationName = AppConstant.GoogleApplicationName
            });

            return true;
        }
