I don’t use Calibre for this (but I do for epub and pdf ebooks). I use Plex and use Plexamp for my music collection. For audio books I used to have Chronicle Audiobook Player installed (which is open source, but not actively maintained) but am now trying out Listen Audiobook Player (which is not open source as a heads up). Both of those allow me to download books wherever I am.

If you have no interest in running a Plex server neither of them are suitable for you, but I just wanted to mention this solution in case you’re not dead set on using Calibre. Plex has a cost factor which may come into play (an obvious non starter for some). I have had Plex Pass for a long time so it was natural for me to use it, but might not be for you.

Maybe you will find Blood, Sweat and Pixels by Jason Schreier of interest. Been a little while but I enjoyed it as an audio book.

Real kidnappers will not be happy about this as deepfake becomes more prevalent and calls for ransom gets ignored more and more. Do they have union that can go on strike to raise awareness about this?
