cookiebot_gtm
This module makes it possible for you to integrate Cookiebot and Google Tag Manager in a fast and simple way. You want this if you want to prevent the placement of cookies and scripts implemented by GTM to run before user agreement.
Simply create a cookiebot profile, a GTM id and insert them on the configuration page and everything works. All other external Javascript can be added via GTM and will be checked by Cookiebot.
If you have a multilingual website, you can also configure how to use those languages. You can set the language of the cookiebanner, and you can set (if you want to) a separate GTM id per language.
This module also creates a page that shows you which cookies are enabled and/or available on your site. This data is being fetched from your cookiebot profile.
