Package registry

Hi.

I’m using self-hosted GitLab Community Edition 12.4.2 and I tired to use package registry functionality that I’ve seen in documentation here:

https://docs.gitlab.com/ee/user/packages/npm_registry/index.html#publish-an-npm-package

to publish my own NPM packages, but I’m having hard time trying to publish them and also I don’t see “package registry” option on menu:

is package registry available for this version of Gitlab?
