How to embed an external cookie solution like iubenda

UI Builder

We have to comply to some laws with regards to the usage of cookies. Here in Europe a service among others is iubenda. They provide me with a code snippet which I have to embed above the HEAD tag of the page. How can I do that?

<script type="text/javascript">
----something in here
</script>
<script type="text/javascript" src="//cdn.iubenda.com/cs/ccpa/stub.js"></script>
<script type="text/javascript" src="//cdn.iubenda.com/cs/iubenda_cs.js" charset="UTF-8" async></script>

See if the approach described here would work for you (it injects a CSS file, but it should work the same way for a JS import):
