如何在模板文字(LitElement)中呈现html标签？

import { html, LitElement } from 'lit-element';

class MyElement extends LitElement {
  render() {
    return html`
      <div>
        <h1>Hello, LitElement!</h1>
        <p>This is an example of rendering HTML tags in LitElement.</p>
        <p>${this.generateDynamicHTML()}</p>
      </div>
    `;
  }

  generateDynamicHTML() {
    // 通过JavaScript表达式生成动态的HTML标签
    const tagName = 'span';
    const textContent = 'This is a dynamic HTML tag generated by LitElement.';
    return html`<${tagName}>${textContent}</${tagName}>`;
  }
}

customElements.define('my-element', MyElement);
