// For example, to use recaptcha:
createScriptLoader({
  src: 'https://www.google.com/recaptcha/enterprise.js?render=my_token'
  onload: async () => {
    await grecaptcha.enterprise.ready();
    const token = await grecaptcha.enterprise.execute('my_token', {action: 'login'});
    // do your stuff...
  }
});

// or pinterest embeds:
const pinterestEmbedScript = '!function(a,b,c){var d,e,f;d="PIN_"+~~((new Date).getTime()/864e5),...';
createScriptLoader({
  src: pinterestEmbedScript,
  onload: () => window?.PinUtils?.build()
});
