I am trying to configure claims mapping for my OpenID identity provider. I have read the thread Solved: External Identity Provider - Power Platform Community (microsoft.com) and am following the documentation from Set up an OpenID Connect provider with Microsoft Entra ID - Set up additional claims.

However, upon registering for the first time, I still see that the emailaddress2 field is empty on my newly created contact record.

Any idea why the contact emailaddress2 field is empty despite mapping the claim? Here is my OpenID configuration as a reference:
