how to moderate FB comments with FB GK4 module

I installed the FB GK4 module and I try to moderate the comments but it's impossible, there isn't the option to do it. Someone knows how can I moderate comments with this module? because I have tried to do everything without results. I would really appreciate the help, thanks!

You need to set module APP ID then just look at facebook developers page :

You can moderate comments from just this plugin inline. If you have specified your app id as the admin, you can moderate all your plugins at http://developers.facebook.com/tools/comments.
