This is an example page that is not handled by launch handling consumer, so it should always simply be navigated.
Why? Because this app is configured to 'focus-existing', and I was too lazy to
figure out how to implement file handling where I loaded the 'home' page and sent files
there. So when you implement your own app, know that if you are
'focus-existing' you'll need to make sure ALL of your in-scope pages have a
launch consumer.
