[Question] How to integrate handlebars with GrapesJS?

Hi, How i can integrate handlebars or other template engine with GrapeJS? I mean to create eg. dynamic component with product details:

const blockManager = editor.BlockManager;

blockManager.add("product", {
  label: "Product",
  type: "text",
  attributes: { class: "fa fa-columns" },
  content: `
    <div>
      <h2>{{product.name}}</h2>
      <div>{{product.details}}</div>
    </div>
  `
});

And show parsed data in GrapeJS editor eg.

<div>
  <h2>Sample product</h2>
  <div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque tristique molestie mi, a commodo quam cursus eget.</div>
</div>

But on export user must get raw data, i mean code with handlebars content. Someone can help?
