How to setup correctly on the site CookieConsent v2.7.1 by orestbida.com

I was trying to insert this feature into a website created with a drag & drop program (WebSite X5 Builder Incomedia). The basic program allows you to insert JS, CSS and HTML code into the page.

Generally, I just put the code in the tag etc. and everything works. Could someone please help me?
