PWA with framework7 and Vue

Ive setup my app using the framework7 cli and Im using framework7/vue and PWA. Im not finding very good documentation on PWA however. Specifically Im looking to popup a notification when a new app update is waiting to be reloaded. I cannot finding any documentation on how to do this with framework7 and vue. Does anyone have a solution?

This is not really related specifically to Framework7 and not related to Vue, it is about service workers, and a lot of such info on the web, for example
