            using var file = File.OpenRead(localPdfFileName);
            var uploadResult = pdfApi.UploadFile(Path.Combine(storageTempFolder, storageFileName), file);
            Console.WriteLine(uploadResult.Uploaded[0]);
        }
    
        var response = pdfApi.GetDocumentProperties(storageFileName, folder: storageTempFolder);

        foreach (var item in response.DocumentProperties.List)
