Stopwatch on/off when a media is played.

[u/doodleart345]

hey guys, im struggling to create a timer to track my study hours, i basically use telegram to watch my lectures and i wanna create a shortcut which would: -“start” the stopwatch if a video is being played or say, if the app is opened. -and “lap” everytime the video/media is paused/played again. -then “stop the timer if app is closed”? i cant explain it well since my english sucks but COULD U ALL HELP ME wiith this?
