Timer on Storyline 360

Hello,

I'm trying to add a timer to my quiz module (which draws 30 questions randomly from 10 question banks) with 60 minutes of time lapse and I can see that the timer keeps running if the quiz window is open but, as soon as I switch the window the timer pauses and when I go back to quiz the timer picks up from where I left.

I'm looking for an option where the time should keep running even when the person taking the quiz switches the quiz window (minimizes or navigates to some other tab).
