C# get credentials from Google Sheets API

I have a problem with get credentials from Google API.
I searched a lot of old topics and can't find solution.

My code looks like:

static readonly string[] Scopes = { SheetsService.Scope.Spreadsheets };
static readonly string ApplicationName = "Dot Tutorials";
static readonly string sheet = "Arkusz1";
static readonly string SpreadsheetId = "1IEvv4enfouBXrGEVLTKeQNYTJIzQHmRNyKTxKAxEAfg";
static SheetsService service;
GoogleCredential credential;
    //Reading Credentials File...
    using (var stream = new FileStream("secret.json", FileMode.Open, FileAccess.Read))
    {
        credential = GoogleCredential.FromStream(stream)
            .CreateScoped(Scopes);
    }
    // Creating Google Sheets API service...
    service = new SheetsService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = ApplicationName,
    });

Secret .json I downloaded :

{
  "installed": {
    "client_id": "1087609048092-hdh5ku57kaamha72o7t3tdtkb62vq5ur.apps.googleusercontent.com",
    "project_id": "excellent-well-151116",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "*********hidden my secret code*******",
    "redirect_uris": [
      "http://localhost"
    ]
  }
}

And when I run it I still am getting the error:

> System.InvalidOperationException: 'Error creating credential from JSON or JSON parameters. Unrecognized credential type .'

I don't know what is wrong here. I'm trying to follow this tutorial: https://dottutorials.net/google-sheets-read-write-operations-dotnet-core-tutorial/

My goal is to get values from this spreadsheet into a DataTable: https://docs.google.com/spreadsheets/d/1IEvv4enfouBXrGEVLTKeQNYTJIzQHmRNyKTxKAxEAfg/edit#gid=0.

Here is what you want:

        UserCredential credential2;

        using (var stream = new System.IO.FileStream(clientSecretsPath, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {
                credential2 = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.FromStream(stream).Secrets,
                    new[] { GmailService.Scope.MailGoogleCom },
                    "my@gmail.com", CancellationToken.None, new FileDataStore("LoginCookieStoredHere"));
            }

            return new GmailService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential2,
                ApplicationName = "Gmail API Example"
            });
        }
