Present FBWebDialogs With Friends That install The App

i want to open FBWebDialogs that present the client friends who use the app

this is my code:

        FBWebDialogs.presentRequestsDialogModallyWithSession(FBSession.activeSession(), message: "xxx", title: "xxx", parameters: ["filters":"app_users"], handler: { (FBWebDialogResult, NSURL, NSError) -> Void in

        })

this query don't filter properly.

i know that i can use "me/friends?filters=app_users" in a Graph API query but i Want to use FBWebDialogs UI in order not to build one myself.
