Method DetokenizeIdentityField

identity.go:217–258

DetokenizeIdentityField detokenizes a specific field in an identity. Parameters: - identityID string: The ID of the identity. - fieldName string: The name of the field to detokenize. Returns: - string: The detokenized field value. - error: An error if the field could not be detokenized.
