Anyone have experience setting up StencilJS with a Phoenix App using webpack?

I’ve installed both packages:
Stencil/Core
Stencil/Webpack

Then, set webpack.config.js:

const stencil = require('@stencil/webpack');

...

  plugins: [
    new stencil.StencilPlugin()
  ]

Finally I’ve created a src/components directory in the assets folder and create a component.tsx:

import { Component, Prop, h } from '@stencil/core';

@Component({
  tag: 'my-first-component',
})
export class MyComponent {

  // Indicate that name should be a public property on the component
  @Prop() name: string;

  render() {
    return (
      <p>
        My name is {this.name}
      </p>
    );
  }
}

When trying to use the component it doesn’t render at all. Am i missing some config somewhere for the compiler?
