I have MS Entra as an identity provider. I'm using the basic_connector OAuth2.0 configuration. After new users log in for the first time, they are asked to verify their email addresses.
I am set up with the "Check Email Verified"/"The OAuth2 site has verified the email" to "yes". It's definitely true that the OAuth2.0 provider has verified all the email addresses. It's a definitive relationship, since the ID provider and email provider are effectively the same, for this class of authenticated & authorized users.
I have tried a variety of values in the "Email Verified JSON Path" such as "verified_primary_email" but none of the options have worked.
