Apple have advice on the assistive touch here: https://support.apple.com/en-ie/HT202658

But you might find that the 'claw' method better suits your needs. Place 4 fingers on the screen and swipe left or right, it will switch between open apps. So if you have the date time  settings open, and then go to the game you can switch between the two screens by 'clawing' across the screen left or right.
