Jest test a removable of a dom element

I have this fonction that removes an element from the dom

export function removeSlot(component: any, selector: string) {
  if (component.querySelectorAll(selector).length > 0) {
    component.querySelectorAll(selector).forEach(el => el.remove());
  } else {
    console.error(`'${selector}' not found in component '${component.tagName.toLowerCase()}'`);
  }
}

So far I have this code

describe('delete element', () => {
  it('delete the element', function() {
    const html = `
      <div>
        <ol>
          <li>
            <a href="https://www.example.com/">lorem</a>
          </li>
          <li>lorem</li>
          <li>
            <a href="https://www.example.com/">
              lorem
            </a>
          </li>
          <li>lorem</li>
        </ol>
      </div>
      `;
    document.body.innerHTML = html;

    removeSlot(html, 'ol');

    expect(document.querySelectorAll('ol').length).toEqual(1);
  });
});

I get errors

Any help would be very much appreciated!
