Emails to users on pushes and other important events

I just installed the Gitlab Omnibus on Ubuntu 18.04. I setup email in gitlab.rb, ran reconfigure, and I am able to successfully send a test email from the gitlab rb console. I’m trying to setup Emails on Push, however the docs say to look in Settings -> Integrations, but I only have “PlantUML” and “Third Party Offers”. Is there something else I need to install? Thanks.

OK I now see “Emails on push” is available through “Service Templates”, however that seems to be a global email for any push to any repo. Is there a way that people setup more fine-grained controls, where users can subscribe to certain events from certain repos on their own?
