Hey @DaveOrDead I'd like a crack at this please assign this issue to me, just curious about one thing though, should the isAuthenticated method simply check if the user is authenticated i.e. the access token in memory is not yet expired or should it also attempt an initial refresh of the access token if it is expired. The kinde-nodejs-sdk for example does perform an initial refresh if the access token is expired as you can see here.

Hey @atifcppprogrammer , thanks for picking this up :)

Attempting an initial refresh sounds like a great enhancement if you're keen for it
