The gyro permission request doesn't work on iOS since it's not tied to user input. If you're feeling brave, you can paste this into your phone's javascript console to add a button that requests permission.

var b=document.createElement('button'); b.textContent='Gyro'; b.style='position:fixed;z-index:999'; b.onclick=()=>{DeviceOrientationEvent.requestPermission();b.remove()}; document.body.appendChild(b);
