What are the options for storing and checking scope in a service?

Question

JSON Web Token

I decided to try rest_framework_sso (based on a private and public key), there is an identification service, the client is identified, receives an encrypted access_token, with the private key of the identification service.
When contacting another service (other), it passes this access token, the service (other) decrypts the token with a public key, and receives data and, of course, scope.
It turns out that I have scope stored on the identification service. And in order to check on the other - service that the client can, I have to store the scope on my own. It is possible to somehow avoid this.
