During the beta of the tag manager, all admins and super users can create tags, triggers, and variables that execute custom JavaScript on your website. As this could break some features of your website or be misused to steal sensitive information, you may want to disable these features. When the Tag Manager is out of beta, there will be new permissions available so you can grant only certain Matomo users access to these templates. For example only to developers.
