Как создать каталог и загружать файлы на общий диск Google вместо диска по умолчанию (мой диск)?

Question

Я пытаюсь извлекать данные из базы данных и динамически создавать каталог на диске Gooogle, используя разные имена проектов, и загружать CSV-файлы в соответствующий каталог. До сих пор у меня не было проблем, но теперь, когда мой проект запускается, мой клиент попросил меня создать каталог.в Общий Google Диск вместо диска по умолчанию, т.е. Мой диск, и я не знаю, как это сделать.

Я включаю код, который я использую - спасибо за любую помощь заранее

private DriveService GetDriveService(UserCredential credential)
{
        return new DriveService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = ApplicationName,
        });
}

//verify User Credentials using client_secret.json file ...
private UserCredential GetCredentials()
{
        UserCredential credential;

        using (var stream = new FileStream("client_secret.json", FileMode.Open, FileAccess.Read)) // passing credentials which stored in Client_secret.json
        {
            string credPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
            credPath = Path.Combine(credPath, ".credentials/drive-dotnet-quickstart.json");

            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                Scopes,
                "user",
                CancellationToken.None,
                new FileDataStore(credPath, true)).Result;
        }

        return credential;
}
