Keep Apple Watch Series 3 display on during 1 particular workout/App?

Is it possible to keep the display of an Apple Watch Series 3 on during 1 particular type of workout/App?

I’m experimenting with the “7 Minute Workout” using the Seven App and would like to see the ring going down to zero for some exercises. Unfortunately the watch blanks the display before the 30 seconds of an exercise have passed.

Is it possible to keep the display of the watch on while running this (or any other) particular App?

(the App itself does not seem to have such a setting on the watch or on the phone)
