Is Allowed Hosts still functional on https://work.google.com/passwordalert ?

[tbakrf]

We set this up many years ago - apologies - we still get reports time to time for users, and the reports direct us to: https://work.google.com/passwordalert (which successfully shows history)

Does anyone know if that site is still functional for whitelisting sites?
We see this at the bottom:

Sites that you have allowed to bypass Password Alert will show up here . To add a domain, search for it from the Password Alert homepage and change its status to “Allow”.

When we go to https://work.google.com/passwordalert/hosts there is no option for "allow".

I'm wondering if the site is grandfathered and that we have to host something separate? Trying to avoid that if possible. Thanks!
