1. i recommend you run this on the simulator, with your phone nearby open to an ethereum wallet.
//i've verified all the autolinking from comm -> wallet -> comm works during the signing process so device/sim are the same, you'd have to tweak your network.json for your macbook's keyserver//
2. connect wallet by tapping QR code, scan QR using physical device and connect
3. tap again to sign a message
4. proceed to be authenticated
