7.1 google analytics opt-out with tag manager without php code?

Hi, does anyone know how to create a google analytic opt-out (and facebook pixel) with tag manager and Squarespace? 
The codes we tried did not work. I think because they were php scripts.
The ones we used in the google tag manager with html link to sign out did not work either.

Is there anyone who has a running opt-out solution? 

Hi. Which code did you use? We can check easier.
