Problem with revoking sso tokens

[bradleyFS]

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"

@JasSuri can we update the readme for this sample so that others don't go down this path if the sample doesn't work

@bradleyFS did you find another solution to this?

I could not get this to work in b2c and an alternative with graph call had to be done outside b2c.
