Insert cookiebot script in head not working

Hi,

I'm adding a cookie notice (GDPR). However when I add the below script via WP_head hook it does not show.
Cookiebot states that I need to add the script to the html header of the website.

This should be WP_head hook right?

<script id="Cookiebot" src="https://consent.cookiebot.com/uc.js" data-cbid="c765ca50-67d7-45aa-a4ef-3d71166e132c" type="text/javascript" async></script>

Thanks
