Safari浏览器中的GetDisplayMedia屏幕截图？

Question

这是生成图像的代码，

console.log('--imageCapture');
const btn = document.querySelector('#btn')
btn.addEventListener('click',()=>{
  screenshot()
})

function screenshot(){
const canvas = document.createElement("canvas");

// Request media
navigator.mediaDevices.getDisplayMedia().then(stream => 
{
  console.log(stream);
  
  let track = stream.getVideoTracks()[0];
  
  let capture = new ImageCapture(track);
  
  capture.grabFrame().then(bitmap => 
  {
    // Stop sharing
    track.stop();
      
    // Draw the bitmap to canvas
    canvas.width = bitmap.width;
    canvas.height = bitmap.height;
    canvas.getContext('2d').drawImage(bitmap, 0, 0);
      
    const frame = canvas.toDataURL("image/png");
  });
})
.catch(e => {
  console.log(e)});
}

这些代码运行 它在Chrome中完美运行，但是不能在Safari中运行，是否有任何方法可以在Safari中生成图像？
