It did note pdfplumber - https://github.com/jsvine/pdfplumber

To automate the creation of a clickable index, you need to use a scripting
language with a library that can read and manipulate PDF files. This is a
multi-step programming task, not a single-tool solution.
------------------------------

The Programmatic Approach

The process involves using a programming language like *Python* with
libraries such as *PyMuPDF (fitz)* or *pdfplumber*. The logic is as follows:

   1.

   *Extract the Index Entries:* Your script must first read the index
   page(s) of the PDF. For each entry, it needs to parse the text (e.g.,
   "Chapter 1: Introduction") and its corresponding page number.
   2.

   *Locate the Destination:* For each entry extracted in step 1, the script
   must then search for the exact same text ("Chapter 1: Introduction") within
   the main body of the document. The page number from the index serves as a
   guide, but the script needs to confirm the text's location on the page to
   get its precise coordinates.
   3.

   *Add the Link:* Once the script has the coordinates for both the index
   entry (where the link will be placed) and the target location in the body,
   it can use the PDF library to create an internal hyperlink. This link, or
   annotation, will be a clickable box on the index page that directs the user
   to the identified page and location in the main document.
   4.

   *Save the New PDF:* The script will save the modified PDF with all the
   new, active links.

This method relies on the assumption that the index text is an exact match
for the text that appears in the main body of the document. This is a
common requirement for successful automation of this task.
