omniauth-facebook authentication with an Angular 2 front end application.

[91sticker]

This might not be an issue its more of a guidance I need regarding the apporoach I am using.
I have a scenario consisting of an angular 2 application with a rails api where I have been able to implement token based authentication using angular2-token package with devise_token_auth gem. The part m confused about is how do I use devise_token_auth to correctly implement omniauth-facebook's authentication through my angular 2 application having a rails API. I have seen the angular code snippet about it provided in the gem's documentation.
Using ng2-facebook-sdk I have been able to login via facebook and get a cookie as a response on the front end. However the part that confuses me is how to send that information I received in the cookie on my front end to the rails api's ''/auth/facebook/callback" endpoint.

Please let me know if this is the correct approach or if I am missing something. If this has been answered I apologize I didnt come across any material that addresses this issue.
Thanks in advance.

I have also posted a question on stackoverflow:
