How do jenkins plugins expose users/groups to the matrix authorization plugin?

[red 888]

I think its safe to say the Google Login plugin is dead: https://github.com/jenkinsci/google-login-plugin

Hasn't been updated in like a year and there are a bunch of old open pull requests.

Id like to modify it for myself to be able to use groups in addition to just users under "Project-based Matrix Authorization Strategy"

How does a plugin expose groups to jenkins?

I have used the Active Directory plugin before with the matrix security and I can just add an AD group and use that for authorization.

How does one present users and groups to the Matrix-based Security plugin? I want to see if I can modify the Google plugin to query a users google groups when they login- i just don't know how i connect this to matrix auth.
