notify-send command with -u critical and -t option

notify-send command with -u critical and -t option

I sometimes see the command :
notify-send -u critical -t 3000 "Example"
However, with -u critical, it seems like the notification doesn't time out. What is the purpose of adding a timeout option then?
Do you have a link which explains exactly what the notify-send does? The ones I found were not very detailed in their explanations.
What is the purpose of the -u option, btw?
