How to redirect the user to login to facebook and have her come back to the same place? Laravel5

I have a dashboard feature that requires facebook login. If the token is expired, I catch that.

So far so good, however, I'd like the user to go off to login and come back to the same place.

This is the code:

    try {
        //make FB client
        $fb = new Facebook( [
            'app_id'                => config( 'app.FACEBOOK_APPID' ),
            'app_secret'            => config( 'app.FACEBOOK_APPSECRET' ),
            'default_graph_version' => 'v2.8',
        ] );

        //Pull events realted to this user
        $events      = $fb->get( $endpoint, $accessToken )->getDecodedBody();

      //catch exception if token is expired
      } catch ( FacebookSDKException $e ) {
        //redirect to facebook login
        return redirect()->action('Auth\SocialiteLoginController@redirectToProvider', ['facebook']);
    }
    return $events;

My issue is, the return redirect() statement, does not redirect the user to Facebook, but, it sends back the RedirectResponse object to the calling function.
