hi team, I followed above docs for Cloudflare login but seem like it does not work, I don't see a button in UI, and as checked the code NewCloudflareProvider is not being used anywhere.

I can use the Google OIDC login alternatively, but there is no function to restrict which email domain can login, for now anyone with google account can login.

Can some one help pointing me to the documentation to restrict users for SSO, many thanks
