[keycloak-user] How to use identity provider broker (google and facebook) via ajax/api

Hello, *Context*: We have a single page application made with Angular JS. We want to implement login via facebook and google, by using keycloak. *Requirement*: We want to use ajax/api call, similar to "../protocol/openid-connect/token" (this end point is using user/pass to login"). *Problem*: The way the brokering works, is with a series of html redirects: start -> redirects to keycloak -> redirects to facebook or google -> back to keycloak -> back to start This is not compatible with a single page application. *Question*: Is there any documentation (or work around) how to achieve login with facebook/google by using ajax/api calls, similar with the one for user/password ("../protocol/openid-connect/token" endpoint)? We need to be able to retrieve the token from facebook and google, and send it to keycloak, and keycloak should respond with the authentication token. How can we do it? Thank you.
