Discussion Authentication Service AccessToken Verification

Hello,

I am using Unity Authentication Service for accessing the other Ugs elements. I've already connected my OpenID provider with Ugs and I've confirmed the user profiles can access i.e Economy service.
I'm building a multiplayer game server in Unity (server authoritative) and I want to verify each message is coming from the authenticated players. As I saw from the references I can retrieve the AccessToken from AuthenticationService object in the client-side. What I am curious about if I pass this token to my custom game server instance can I somehow call the Authentication Service to verify this token ? If this not the case what should be the proper way to verify the client's messages ?

Thanks in advance !
