  const el = document.createElement('textarea');
    el.value = str;
    el.setAttribute('readonly', '');
    el.style.position = 'absolute';

    document.body.appendChild(el);
    const selected = document.getSelection().rangeCount > 0 ? document.getSelection().getRangeAt(0) : false;
    el.select();
    document.execCommand('copy');
    document.body.removeChild(el);

      document.getSelection().addRange(selected);
