How do you prevent a foreground notification from displaying?

[danleveille]

Scenario: A user can set a timer in my app. If the app is closed, they get a notification. If the app is open, however, I only want them to get a notification if they aren't on the "Timers" screen (since it's clear that the timer has ended).

Is there a way to suppress push notifications while in the app?

I could use notifee.onForegroundEvent to listen for the the "DELIVERED" event, but is there are way to prevent it from actually delivering or displaying?
