Azure AD B2C Claims do not include mapped Custom IdP claims

Question

I have Azure AD B2C directory and have added our other separate Azure AD (AAD) as an Identity Provider (as Open ID Connect Provider) in Azure AD B2C. I am able to sign in just fine using the custom IdP which links to AAD.

I also have Identity provider claims mapping set as "User ID" to oid, "Display name" to name, "Given name" to given_name, "Surname" to family_name and "Email" to preferred_name (per following link). But when I get the token back and inspect it using https://jwt.ms/, it does not have those claims. When I inspected the "idp_access_token" claim and it has oid, given_name, family_name etc. returned by AAD. I'm not sure where I'm missing. I want these claims to be in the token issued by B2C.

Any help is appreciated.

I have selected all of these "Application Claims" in my user flow

You probably missed a step: Configuring optional claims.
