How do I use a react-web-component component in a vanilla js file tied to an HTML file

I created a simple React component.

const ReactComponent = () => {
   const [name, setName] = useState("something");
  return <div>Hello {name}</div>
}
export default ReactComponent;

And I used react-to-webcomponent library to convert it to a plain HTML tag which gives me tags which I can use in any page. But I want to use it inside a standalone HTML page with vanilla js.

index.html

<script async defer src='index.js'></script>
<body>
<div id='main>Hello World</div>
</body>

index.js

import {initComponent} from '/ReactComponentWC.js'
const main = document.getElementById("main");
initComponent(main)

In ReactComponentWC.js

const initComponent = (containerElement) => {
    const reactElement = r2wc(ReactComponent, React, ReactDOM)
    customElements.define("react-component", reactElement)
    const myComp = document.createElement('div')
    myComp.innerHTML = `<react-component />`
    containerElement.appendChild(myComp)
}

export { initComponent }

When I load the index.html on Live Server, I get this error
‘Uncaught TypeError: Failed to resolve module specifier “react”. Relative references must start with either “/”, “./”, or “../”.’

Then I tried to bundle the ReactComponentWC.js file using webpack. Now when I imported from the bundled /dist/ReactComponent.js file, it showed “no export named initComponent found”

. This import works fine in any nextjs page in my app. The error occurs only in this standalone HTML page.

Any suggestions on how I can export my react component so that it can be used by any JS frontend framework or even vanilla js apps? Thanks in advance!
