// Makes an authorization decision about a service request described in the
// parameters. The principal in this request comes from an external identity source
// in the form of an identity token formatted as a JSON web token (JWT) (https://wikipedia.org/wiki/JSON_Web_Token)
// . The information in the parameters can also define additional context that
// Verified Permissions can include in the evaluation. The request is evaluated
// against all matching policies in the specified policy store. The result of the
// decision is either Allow or Deny , along with a list of the policies that
// resulted in the decision. If you specify the identityToken parameter, then this
// operation derives the principal from that token. You must not also include that
// principal in the entities parameter or the operation fails and reports a
// conflict between the two entity sources. If you provide only an accessToken ,
// then you can include the entity as part of the entities parameter to provide
// additional attributes. At this time, Verified Permissions accepts tokens from
// only Amazon Cognito. Verified Permissions validates each token that is specified
// in a request by checking its expiration date and its signature. If you delete a
// Amazon Cognito user pool or user, tokens from that deleted pool or that deleted
// user continue to be usable until they expire.
