Clarify how to access "admin area"

In page https://docs.gitlab.com/ee/integration/oauth_provider.html / GitLab as OAuth2 authentication service provider

Page states, "To create an application that does not belong to a certain user, you can create it from the Admin Area."

I can't figure out how to access the admin area. Searching HELP didn't provide any insight(?)

I'm attempting and failing to provide access to stackeditDOTio to one of my GitLab repositories.
