Upload a file to Google drive does not work!

Hi

I'm trying to upload a file to google drive using google drive Api in my core 2.1 project, So I followed these instructions:

https://developers.google.com/drive/api/v3/quickstart/dotnet

But it doesn't work.

The Google Drive Api settings in Google Cloud Platform:

Api is enabled:

Credentials:

Authorized redirect URI:

Of course I've copied the credentials.json json file to my project directory as mentioned in the instructions.

Orders model property (which I want to attach the file to):

public string WorkURL { get; set; }

Upload method:

        public void Upload(string path)
        {
            UserCredential credential;

            using (var stream =
                new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
            {
                // The file token.json stores the user's access and refresh tokens, and is created
                // automatically when the authorization flow completes for the first time.
                string credPath = "token.json";
                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    Scopes,"user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;
                //Console.WriteLine("Credential file saved to: " + credPath);
            }

            // Create Drive API service.
            var service = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            // Define parameters of request.
            FilesResource.ListRequest listRequest = service.Files.List();
            listRequest.PageSize = 10;
            listRequest.Fields = "nextPageToken, files(id, name)";

            // List files.
            IList<Google.Apis.Drive.v3.Data.File> files = listRequest.Execute()
                .Files;


        }

OrdersController:

    public class OrdersController : Controller
    {
        private readonly ApplicationDbContext _context;
        private string[] Scopes = { DriveService.Scope.Drive };
        static string ApplicationName = "CoreWebApp";


        public OrdersController(ApplicationDbContext context)
        {
            _context = context;
        }

        [HttpPost]
        public async Task<IActionResult> Edit(int id, [Bind("Id,WorkURL")] Orders orders)
        {
            if (id != orders.Id)
            {
                return NotFound();
            }

            if (ModelState.IsValid)
            {
                try
                {
                    Upload(orders.WorkURL);
                    _context.Update(orders);
                    await _context.SaveChangesAsync();
                    ViewBag.mess = "Saved";
                }
                catch (DbUpdateConcurrencyException)
                {
                    if (!OrdersExists(orders.Id))
                    {
                        return NotFound();
                    }
                    else
                    {
                        throw;
                    }
                }
            }
            return View(orders);
        }

Getting the file in Edit view:

<div class="form-group"><label asp-for="WorkURL" class="control-label"></label><input asp-for="WorkURL" type="file" class="form-control" /><span asp-validation-for="WorkURL" class="text-danger"></span></div>

But when choosing some file and save the data no file is uploaded to google drive and no action happened but saving.

Why? and how to solve?
