Non SSO Users not receiving password expiration warning notifications in OCI GEN 2

Summary:

The majority of our users are SSO, however our Admins and service account profiles are not set up for SSO.

The non-SSO users are not receiving any email notifying them of their upcoming password expiration.

I have reviewed the Notification Options for our domain, and I don't see any options regarding password expiry notices.

Is this not an option in the OCI Gen 2 environment? Is there another way to ensure non-SSO users receive notifications of upcoming password expiration?
