I want to create a new pdf file by merging multiple files using PDFTron. But when I am trying to add a bookmarks like table of contents, Cover page etc. then I am unable to create it. As I have tried many code samples posted in the community and also from Samples that we can find out in Download section (https://dev.apryse.com/windows) but still I am unable to get the desired results. I am using PdfTron latest version

First I am merging multiple files, then I am trying to create the table of contents and Cover Page etc. But I have used multiple combinations of codes from official website as well but nothing is working for me.
I want to merge files from folder into PDF then need to create/add a Cover page, Table of Contents etc.
