Pair a remote with no internet

Step by step: pair a remote with no internet

1. Turn on a hotspot. No Wi-Fi on set? Turn on the hotspot on either phone and join the other device to it. No internet is needed after that.
2. Pair → No internet. On the prompter, open Pair and choose No internet. It shows a QR code that holds the whole connection offer.
3. The phone scans it… Scan with the phone. It opens the remote and shows an answer code of its own.
4. …and the prompter scans back. Hold the phone up to the prompter’s camera. The two devices link directly over the hotspot, with no server in between.
