Custom Repositories . . . Missing?

I am trying to add a “Custom Respository” like described in this article: https://hacs.xyz/docs/faq/custom_repositories/

I am running the latest version of Home Assistant Supervisor. When I click on the three dots, the only option I get is “Application Credentials”.

Any help would be appreciated.

Thanks!

Screenshot with context, please

You sure you click the three dots within the HACS user interface and not within Integrations?
