How to import client-side HTML into Gatsby/React?

I’m a react noob and self-taught, so I’m sure I am doing something stupid. I’m trying to make a small bit of client-side rendered html into a component within my Gatsby site. Been battling this for 4 days. I'm desperate to get this Vue component into my Gatsby site.

Here's the code for my component:

import React, { Component } from "react"
import { Helmet } from "react-helmet"
import DemoHTML from '../../static/demo.html');


class Model extends Component {
  componentDidMount() {

    // set up and use external package as needed

    const Mount = React.createClass({
        render: function(){
          return (
            <section contentEditable='false' dangerouslySetInnerHTML= />
          );
        }
      });
  }
  render(props, Mount) {
    return (
      <React.Fragment>

<Helmet>

<script type="text/javascript" src="https://unpkg.com/vue"></script>
<script type="text/javascript" src="https://unpkg.com/zircle"></script></Helmet>
<Mount></Mount>
      </React.Fragment>
    )
  }
}


export default Model;

Then, here is the HTML that is imported:

                    

<div id="app">
  <z-canvas :views='$options.components'>
  </z-canvas>
</div>

    <script>

const one = [
    template: `
    <z-view style="border-color: #8F6AFA; font-family: 'Montserrat', sans-serif; font-weight: bold; color: #ffffff; border-width: 1px; background-image: linear-gradient(90deg, #292929 2.11%, #000000 104.85%)" />
` ]

    new Vue({
      el: 'app',
      components: {
        one
      },
      mounted () {
        this.$zircle.setView('one')
      }

    })
</script>

Lastly, here's my errors in console and on page...

On page error:

Unhandled Runtime Error

One unhandled runtime error found in your files. See the list below to fix it:


Error in function createFiberFromTypeAndProps in ./node_modules/react-dom/cjs/react-dom.development.js:25058
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of `Model`.

./node_modules/react-dom/cjs/react-dom.development.js:25058
Open in Editor
  25056 |           {
  25057 |             {
> 25058 |               throw Error( "Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: " + (type == null ? type : typeof type) + "." + info );
  25059 |             }
  25060 |           }

It's helpful to note that the HTML page does render perfectly on its own.

Thank you!

UPDATE

I have made the suggested update to ESM (and also updated in the question. One thing I wanted to share with you all, in case it warrants consideration. The reason this script must be rendered on client side is it is a vue library. (See Zircle.github.io)

If everything is loaded client side, I don't see why this would be an issue. But, just an FYI.
