I have a PWA (progressive web app) that in short displays a searchable list of PDF documents. Tapping on one of the items in the list brings up the PDF in the native view on the iPhone, which all works great. My issue is when doing this I loose the back button to return to the list. I would like to create my own top menu bar with a title and back button to return to the list as swiping back isn’t intuitive to all users and doesn’t exist if the PWA is viewed in Windows.
