Help needed for adding/detecting Bookmarks and links to it

Hello. Could you provide a solution how could I add and detect bookmarks and links to it using Aspose.PDF library ?

I attached the pdf file which I would like to compose with Aspose.PDF library.

I tried detecting bookmarks with code below but it returns null

PdfBookmarkEditor bookmarkEditor = new PdfBookmarkEditor();
bookmarkEditor.bindPdf("C:\\Bookmarks.pdf");

var bookmarks = bookmarkEditor.extractBookmarks();

Bookmarks.pdf (27.5 KB)

Can you please try with a PDF that has bookmarks defined in it. We checked your document and looks like it does not have any bookmarks.
