TODO
Make timer count down even when app is un-focused or closed.
Set const endTime = Date.now() + duration and save that to the task, maybe?
Then trigger notif when endTime == Date.now()?
Then fetch endTime from DB -> if null then timer is inactive
if !null then set timer to endTime - Date.now() and start
Might have to save duration as well in DB to preserve timer animation persistance
