How to identify if access token is a client token or a user token?

[sagarshah1983]

Hello everyone,
Is there a good/ideal way to determine the token type (client token or a user token) in Ory Hydra?
I am thinking of using and comparing client_id and sub field values and consider it a client token (if sub and client_id matches) else consider it as a user token.
Is that a good approach?
Can I consider any other fields/claims from access token to derive to this?

Appreciate your suggestions!

The way you do it right now (comparison) is probably the only way to distinguish the token type!
