        using var file = File.OpenRead(localPdfDocument);
        var uploadResult = await pdfApi.UploadFileAsync(storageFileName, file);

        // Create new bookmark with input parameters for the PDF on cloud storage.
        Bookmark bookmark = new Bookmark(
                    Action: "GoTo",
                    Bold: true,
                    Italic: false,

        );

        // Replace a bookmark with bookmarkPath in the PDF on cloud storage.
        BookmarkResponse response = await pdfApi.PutBookmarkAsync(storageFileName, bookmarkPath, bookmark);

        // Checks the response and logs the result.
        if (response == null)
            Console.WriteLine("BookmarksReplace(): Unexpected error!");
        else if (response.Code < 200 || response.Code > 299)
            Console.WriteLine("BookmarksReplace(): Failed to append bookmark to the document.");
        else { // Downloads the updated file for local use.
            await (await pdfApi.DownloadFileAsync(storageFileName))
                .CopyToAsync(File.Create(Path.Combine(localFolder, resultFileName)));
