SPFx with Bing Maps render empty divs

I have SharePoint 2019, and I am trying to create a webpart that will display Bing Map, I tried this on a react app created using create-react-app, and it works fine. Then I took the code, and added it to SPFx, I am getting no errors, but the div that's supposed to render the map is empty.

Here's my code for the root component:

 return (
      <div>
        <BingMap />
      </div>
    );

Then I have a utility function that'll load scripts when called:

const loadDynamicScript = (config, callback) => {
    const existingScript = document.getElementById(config.id);

    if (!existingScript) {
      const script = document.createElement('script');      
            script.src = config.link;
            script.id = config.id;      
            document.body.appendChild(script);      
            script.onload = () => {
        if (callback) callback();
      };
    }

    if (existingScript && callback) callback();
  };

  export default loadDynamicScript;

Then I have my BingMap component:

import * as React from 'react';
import scriptLoader from '../../utils/scriptLoader'

const config = {  
      id: 'bingmaps',    
      link: 'https://www.bing.com/api/maps/mapcontrol?callback=GetMap&key=[mykey]'
}

declare global {
    interface Window { Microsoft: any; GetMap: any }
}window.Microsoft = window.Microsoft || {};window.GetMap = window.GetMap || {}; 


export default class BingMap extends React.Component<{}, {}> {    
           myRef: any;

     GetMap = () => {
      new window.Microsoft.Maps.Map(this.myRef, { });
          componentDidMount() {        
               console.log(this.myRef)        
               window.GetMap = this.GetMap;        
                scriptLoader(config, null)
    }    render() {
        return (
            <div ref={(myDiv) => { this.myRef = myDiv; }} className="map" ></div>
        )
    }
}

So when my component is mounted, it'll call the script loader, and load bing maps, and execute my callback function. This works in create-react-app, but in SPFx it's not, and I a not getting any errors in the console.

It generates this div:
