React-native FBSDK with rails omniauth

[faforus]

Through the sdk I am able to obtain access token along with profile information. That however takes me one step further than required.

Rails with omniauth-facebook expects a lower level 'code/token' in order to get the the higher level access token and than the profile information. Without the lower level token I am unable to use the rails library. And with the fbsdk it appears that I am unable to obtain the lower level token, or am I?

I could potentially be sending the profile data directly from the mobile app to the backend to create/log in users, but that poses potential security risk.

The code I am talking about is mentioned here.

Does anyone have a solution for this?
