How can I add script.js? about browser-extension-react-typescript-starter HOT 3 CLOSED

import pageContextInject from './injection/pageContextInject?script&module';

const setupInjectPageContextScript = () => {
  const s = document.createElement('script');
  s.src = chrome.runtime.getURL(pageContextInject);
  s.type = 'module';
  document.head.appendChild(s);
  s.onload = function () {
    s.remove();
  };
};

(async function initialize() {
  const config = await getExtensionConfig();
  if (config.enabled) {
    //setupInitialDispatch();
    setupInjectPageContextScript();
    //setupInjections();
    //setupSomeOther();
  }
})();

declare module '*?script&module' {
  const src: string;
  export default src;
}
