This currently does not work. refreshTokensValidFromDateTime is a string and in the base file and used in the extensions file as a partnerClaimType. This doesn't match with the refreshTokensValidFromDateTime_for_revoke_sso_sessions claim which is a dateTime.

An example of the error it causes: "B2C_1A_signup_signin has OutputClaims with PartnerClaimType refreshTokensValidFromDateTime with different data types. A PartnerClaimType may only be associated with OutputClaims of same data type"
