Deep Links to epub books in Apple Books

I was just wondering if anyone has cracked the Deep Links to epubs in Apple Books? There is a promising approach in the Hookmark forum Hookmark to Keepit extractor but alas as a DTP user it is unusable.

Does anything similar exist for DTP? Can this be adapted for DTP?

There’s no one working on it that I’m aware of. Apple Books is not talked about much in our forums and support.
