Your app is not notified when it is closed/backgrounded, until the user interacts with it.
From the Expo 38 release notes:
If the notification is triggered while the app is in background,
it’s presented immediately
the application is not informed of this
If the notification is triggered while the app is in foreground,
the application not only receives immediate information about this, but…
it can also decide at runtime whether to display a heads-up alert or play a sound! (For more information see the Notification Handler documentation.)
From the Notifications overview, there are 2 listeners:
addNotificationReceivedListener - This listener is fired whenever a notification is received while the app is foregrounded
addNotificationResponseReceivedListener - This listener is fired whenever a user taps on or interacts with a notification (works when app is foregrounded, backgrounded, or killed)
The Notifications SDK is a good reference as well.
