Accessing the Graph API with client token

[szarbartosz]

Hi 👋

I wanted to start a discussion on the following use-case:
I have a mobile app (developed with expo) in which users can authenticate using react-native-fbsdk-next. After successfull authenticaiton I'd like to pass a client token to my backend, and query Graph API there, in order to obtain user email.

I tried to access the Graph API with tokens obtained by calling:

• AuthenticationToken.getAuthenticationTokenIOS()
• AccessToken.getCurrentAccessToken()

after logging in with LoginManager.logInWithPermissions(['public_profile', 'email']), but failed to do so (either got Bad signature or Malformed access token error)

I was able to query the Graph API using GraphRequestManager on the client side, but I guess that my question is: Is there a way to to do on server side?

Side note: I am aware of the following statement in the docs: "Limited Login is required for iOS if using React Native FBSDK Next >= 13.0.0" - but there is also another statement: "Graph API requests cannot be made with a Limited Login AuthenticationToken" - does it mean that there is no way of obtaining the accessToken on iOS that will allow Graph API access outside of GraphRequestManager?
