Downloading hardcopy book

I am enquiring about how I scan a hardback book barcode with my iPhone 13 to load it into my Logos software.  It is an ebook that yLogos also sells (Bruce Waltke's Genesis A Commentary).

I don't own any Apple products, but I would expect the mobile app for the iPhone to have a barcode scanning feature, just as my app for the Android phone has. This mobile feature will probably only become active once you own the Print Library feature in your base package.

An alternative to the barcode scanning is to search that book in the desktop application's "add to library" tab and just add it there
