I'm trying to detect a shake event on iPhone. shake.js library is not working, would appreciate any help or other solutions. I've also tried this but no luck.

function ClickRequestDeviceMotionEvent () {
window.DeviceMotionEvent.requestPermission()
.then(response => {
  if (response === 'granted') {
    window.addEventListener('devicemotion',
      () => { 
          //alert('DeviceMotion permissions granted.'); 
          
          var o = 0.6; // 0
          var myShakeEvent = new Shake ({
            threshold: 10, // 15. optional shake strength threshold
            timeout: 1000 // optional, determines the frequency of event generation
          });
          
          myShakeEvent.start(); // mobile, no ipad

          window.addEventListener('shake', shakeEventDidOccur, false);
          
          function shakeEventDidOccur() { // function to call when shake occurs
            alert('shake!');
          } 
      },
      (e) => { throw e }
  )} else {
    alert('DeviceMotion permissions not granted.')
  }
})
.catch(e => {
  alert(e)
})

}
