More WiFi Settings (During setup on devices without a Home Button)

Some help please.

When a user is setting up a device in the business, and they accidentally select the Corp WiFi (which blocks activation of the iPhone), I used to be able to tap the Home Button and a menu would pop up from the bottom and I would be able to select WiFi Settings. From here I would be able to "Forget this Network" and then the user would be able to setup the phone using the Cellular Connection without restrictions.

However, on the new iPhone's that have no Home Button, I want to know how to get to the menu that allows me to open the WiFi settings as seen below in the photo of an older iPhone with a Home Button.
