A Live Activity relies on its app being in the background , but contrary to a widget it does not have a timeline.
Our app "in the making" is sandboxed and does not need to receive ActivityKit push notifications
How is the app "maintained in life" and not entirely killed for the duration of the activity - Apple documentation says up to 8 hours ?
Is it necessary for us to do something to maintain it, like to trick the system , play a white noise audio background ...?
