The commitment banner is not working

The Commitment Banner will not work as it seems, this is Code and WIX language is JavaScript. Would you have the code on Java Script?

Unfortunately, we don’t provide yet the Commitment Banner in Java Script. But there is a way to integrate HTML in WIX. Please have a look here: https://support.wix.com/en/article/wix-editor-using-iframes-to-display-visible-content-on-your-site
