How to redirect after submit in Youform embed

If you are embedding Youform in your website and have a redirect set in your thank you page, then you need to add the following code in your page as well for the redirect to work. 
<script>
    window.addEventListener('message', function(event) {
        if (event.origin !== 'https://app.youform.com') return;
        const data = event.data;
        if (data && data.name === 'youformRedirect' && data.url) {
            window.location.href = data.url;
        }
    });
</script>
You can put this code before your closing </body> tag.
