How to send invitation to Facebook friends on iOS using Cordova?

[Doyban]

With exactly the same codebase I have perfectly working Facebook events on Android. However, on iOS it doesn't works. I'm using https://github.com/jeduan/cordova-plugin-facebook4 for this and tried to set some alerts to see the error code or something (note `alert` in the code, for debugging purposes), but there is no action. In essence, I can't see any error, it just doesn't works. The following code:

this.options = {
  method: 'apprequests',
  message: 'Play YellowSidd with me!'
};
this.onSuccess = function(result) {
  alert("Success with invite, result: " + result);
};
this.onError = function(msg) {
  alert("Failed with invite, msg: " + msg);
};
    
facebookConnectPlugin.showDialog(this.options, this.onSuccess, this.onError);

In the Xcode in Build Phases -> Compile Sources I do have FacebookConnectPlugin.m. In Build Phases -> Link Binary with Libraries I do have also the following: libsqlite3.dylib (added by me), Security.framework (added by me), Accounts.framework (added by me), Social.framework (added by me). Also, the FBSDKCoreKit.framework, FBSDKLoginKit.framework and FBSDKShareKit.framework. These last 3 were already in that project.
