How do I add support for a hardware BACK button to an app?

Question

Windows phone

The application is made according to the C# HTML5 template (WP Silverlight),
initially it does not support the hardware back button,
the application consists of a bunch of html pages,
navigation is carried out using the appbar back button,
this is not very convenient, how to make support?,
thanks in advance!)
