Audiobooks not showing on Books App search

Hi,

Following article: Listen to audiobooks in Apple Books - Apple Support (MT) I seem to be unable to find audiobooks anywhere and I don’t have the option to specifically search for audiobooks only for instance. I’ve checked all the settings and reinstalled the app. Updated also to iOS16.1. Screenshots included.

For example I am searching for Atomic Habits by James Clear which I know for a fact has an audiobook version but only the readable one shows up. I’ve also tried with Harry Potter and some other books just to test.

Thanks for the help!
