Need clarify the behavior of QR Code button on `Tap to Pay on iPhone` Figma design

Hi Apple team, We're planning to integrate Tap to Pay on iPhone feature in our product, and found there's a QR code button on the your Figma design: https://www.figma.com/design/2SOXmeLvimllvT67MTMLOy/Tap-to-Pay-on-iPhone--Community-?node-id=0-1&t=E3XskpsLctTuZvg5-1 Questions:

  1. is there any official documentation about the QR code button on this screen?
  2. What happens when user clicks on QR button?
  3. What're the suggestions to show/hide that button, and can we customize it?

Thanks.
