OAuth2.0 플러그인에서 사용자 auth0 sub 값 가져오기

Hello! I am trying to make an api call to an external website that requires the discourse user’s auth0 sub as a parameter. I currently have local signup disabled (so all discourse users are logged in through auth0). OAuth2.0 plugin

On my discourse instance, how can I access the current user’s auth0 sub to then pass to said api call?

Any help is greatly appreciated! Thank you!
