[Improvement] Reduce click/tap after successful payment

[CabtonWithaK]

AS IS
When you Open TPOS > Add items > Shopping Cart > press "Pay" and the invoice is paid > a Screen with a green checkmark is displayed.
When the checkmark is clicked, you arrive on a screen with amount, "pay" (disabled button), "clear cart" (nonfunctional button)

To go back you need to swipe this screen away

TO BE:
When successfully paid and clicked on the checkmark, the screen with amount (0 sats), "pay" (disabled button), "clear cart" (nonfunctional button) should automatically disapear (or slide out)
