Findaway posts a notification specifically for when the user has reached the very end of the audiobook.

Prompt the patron with an Alert View to return the audiobook when this fires.

They can choose to either keep or return the book. If they choose to return it, dismiss the player view and execute the revocation as if the user has hit the "return" button.

Include a way to track patron's usage , sort of analytics (discuss Bugsnag or something else)

Acceptance Criteria:

When a listener reaches the end of an audiobook (last chapter), after around 5 seconds the dialog should appear on screen.

Check to see what happens if the audiobook plays and ends while the screen is locked/off.

Check to confirm if selecting "Return" actually returns the audiobook.

If the Return fails, (disable internet before tapping 'Return'), make sure the loan's state is correctly reflected in the My Books tab, where you can again attempt to return at a later time if necessary.

Confirm that tapping "Keep" does nothing other that dismiss the popup.

Confirm behavior of attemping to hit the "back" button on android while the popup is open.
