Hey could someone give me a hint on how to get going with 3rd party authentication in graph.cool (docs say its possible with resolver functions) but whats the postback url for the oauth service? I dont want to use auth0

Depending on what 3rd party provider you are wanting but I am in the next couple days going to integrate with firebase auth following this guide from one of the other members: https://gist.github.com/FredyC/e9c79301761859c111b9b1ff6880ff0e
