I would like to allow users of my webapp to add passes to Apple Wallet and Google Pay via their respective add-to-wallet-buttons. The aztec code I intend to use on these passes has many data layers, however, both Apple Wallet and Google Pay passes only display barcodes in a small size.

Does anyone know if there are any problems to be expected with bigger aztec codes? Also, are there any recommendations on maximum aztec data layers for Apple Wallet and Google Pay passes? I've been searching through the documentation but can't seem to find detailed info on recommended barcode specifications.
