Is there a way with Google App Script to highlight text in a document when it is modified?

Question

I'm trying to figure out if there's a way to highlight text in colour when it's modified in a Google document. It should simply be coloured if someone changes the text. Is such a thing possible and how do you implement it as a layman?

Thank you for your answer!

Show us the code you have written so far. Did you take a look at https://developers.google.com/docs/api/reference/rest/ ? — Aedvald Tseh, Aug 15 '19 at 09:54

Unfortunately the trigger `onEdit()` only works for Google Spreadsheets

If you want to want to retrieve modifications made in a Google Docs document, there is a rather convoluted workaround I can think of.

Retrieve your revision history with Google Drive API - can be accessed within Apps Script with Advanced Drive Service
Retrieve the revision's exportLinks and download them as text\html . See here for more information
Retrieve the revision test as contents of the exportLinks Url
Pass the revision text to a function to highlight text

Maybe just seeing the revision history (where latest changes will be highlighted) will be sufficient for your purposes.
