3D FlipBook - How to get a specific page content from a template + a dynamic PDF URL

Hi, In my case, I always have a dynamic url PDF. So I'd like to use templates in those PDF but without affecting the PDF pages content, just adding some HTML/audio in the pages that I selected in the template... how can I do that? Because If I use a shortcode like:

[3d-flip-book pdf="https://www.xxxxxxxxxxx.pdf" book-template="XXXX"][/3d-flip-book] --> The dynamic PDF it is showing but not the specific HTML content of page 1, 2, 3...

or

[3d-flip-book pdf="https://www.xxxxxxxxxxx.pdf" id="12474"][/3d-flip-book] --> The specific HTML of page 1,2,3 it is displayed, but not the dynamic PDF link (it takes the PDF uploaded from the template).

How can I do it in my case?

Thanks!
