You can achieve the countdown to run on every scene by creating a script like the one below and then just assign it on a gameobject on the screen (if the script it’s not running by itself)

void Start()
{
 StartCoroutine(Countdown);
}
IEnumerator Countdown()
{
 //set wait time
  yield return new WaitForSeconds(1);
 //do something
}
