Brooklyn with GTM (Google Tag Manager)

I’m trying to install Google Tag Manager in my Wordpress site with Brooklyn.
using GTM code inside Advanced > SEO > Google Analytics ID doesn’t work, so I guess it needs to be in another place.

My template is up to date and it suppose to support GTM, but documentation for Brooklyn is one of its worse sides.

Any help (without extra plugins)?
