Overview

Handles the OAuth callback from the IdP. Wiring:

# config/routes.rb (or inside ActiveAdmin::Devise.config)
devise_for :admin_users, ActiveAdmin::Devise.config.merge(
  controllers: {
    omniauth_callbacks: "active_admin/oidc/devise/omniauth_callbacks"
  }
)

The action name matches the provider name registered with Devise (‘:oidc`, from ActiveAdmin::Oidc::Engine::PROVIDER_NAME).
