Remote inspection for iOS Books

I can inspect an ePub book in Books on Mac using Safari’s web inspector. I can also inspect a web page in iOS Safari when the phone is plugged in to my mac using desktop Safari’s web inspector. What I don’t seem to be able to do though is debug iOS Books remotely using desktop Safari’s web inspector. Given that I’ve got an issue that’s only occurring in iOS Books and not in Mac Books, this is rather annoying. Does anyone know if this is possible?
