Don't use "Wait" for such huge delays! You have no control over it, you can't pause the game, you can't cancel the delayed actions, you can't check how much time is left..
Use Timer behavior. Start a Timer for 60 seconds. While the Timer is running, ignore clicks. On Timer event re-enable the group and set the text visible.
You can save the remaining time into Local Storage every 1 second or so (don't do it too often!). When the game is restarted, check if the timer value exists in local storage, and if it it does - start the timer for the remaining time.
