/**
   Reads current authentication token from the tokenStore and returns
   the following information:

   - scopes: list of scopes associated with the access token in store
   - isAnonymous: boolean value indicating if the access token only grants
     access to publicly read data from API
   - isLoggedInAs: boolean value indicating that the operator has logged in as
     a marketplace user

   Changes to `ctx`:

   - add `res`
