Property 'registerElement' does not exist on type 'Document'. Did you mean 'createElement'?

[VladimirTambovtsev]

With typescript starter with create-react-app I got the following error: Property 'registerElement' does not exist on type 'Document'. Did you mean 'createElement'?

const proto = Object.create(HTMLElement.prototype, {
  attachedCallback: {
    value: function () {
      const mountPoint = document.createElement('span')
      const shadowRoot = this.createShadowRoot()
      shadowRoot.appendChild(mountPoint)
      ReactDOM.render(<App />, mountPoint)
      retargetEvents(shadowRoot)
    },
  },
})

document.registerElement('my-custom-element', { prototype: proto })

I know this is a problem with type, but looks like registerElement is deprecated. Should we use window.customElements.define(...)
instead?
