How to use the detect-gpu.getGPUTier function in detect-gpu

function init() {

  GPUTier = getGPUTier({
     mobileBenchmarkPercentages: [10, 40, 30, 20], // (Default) [TIER_0, TIER_1, TIER_2, TIER_3]
     desktopBenchmarkPercentages: [10, 40, 30, 20], // (Default) [TIER_0, TIER_1, TIER_2, TIER_3]
   });

   //console.log(GPUTier);
  const log = 'devicePixelRatio=' + window.devicePixelRatio + ', applied: ' + getBestPixelRatio() + ' tier=' + GPUTier.tier + ' type=' + GPUTier.type;

  document.querySelector('.log').innerHTML = log;

  realToCSSPixels = getBestPixelRatio();
  fps = getBestFPS();
  interval = 1000 / fps;

  stats = new Stats();
  stats.showPanel(0); // 0: fps, 1: ms, 2: mb, 3+: custom
  document.body.appendChild(stats.domElement);

import { getGPUTier } from 'detect-gpu';

  // forceRendererString: 'Apple A11 GPU', // (Development) Force a certain renderer string
  // forceMobile: true, // (Development) Force the use of mobile benchmarking scores
});
