How do I implement Coloris npm package as a custom element?

I have been trying to implement an NPM called Coloris, to provide end-user color customization capability to a Wix website through a web component. From what I can see, the javascript isn't working/executing. I've tried a few solutions for getting javascript to work in innerHTML, but they haven't worked so far. This issue has stumped me for a week and I still can't get the Coloris color picker to show/render. I can get as an HTML/IFrame embed, but need to make it work as a custom component

Below is the code for the web component. Any help/solutions would be greatly appreaciated

const createScript = () => {

const scriptElement = document.createElement('script');

scriptElement.src = "https://cdn.jsdelivr.net/gh/mdbassit/Coloris@latest/dist/coloris.min.js";

scriptElement.defer = true;

scriptElement.async = true;

return scriptElement;

}

const template = document.createElement('template');
template.innerHTML = `
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/mdbassit/Coloris@latest/dist/coloris.min.css"/>
<script src="https://cdn.jsdelivr.net/gh/mdbassit/Coloris@latest/dist/coloris.min.js"></script>
<input type="text" data-coloris>
`


class ColorisImp extends HTMLElement {
  
  connectedCallback() {

    this.attachShadow({mode: 'open'});
    this.appendChild(createScript());
    this.shadowRoot.appendChild(template.content.cloneNode(true));
   
  
  }
  

  
}

window.customElements.define('coloris-implement', ColorisImp);
