How to get the parameters and pass to the Model

Question

Good afternoon. I`m using mvvmCross 5.2.0 and Xamarin.

I am trying to pass three parameters through a link and when opening my App, treat them in a Model, however I am not able to find how, by AppDelegate, I call a Model passing the parameters.

Link:

valdemar://?token=1234&name=Rafael

AppDelegate:

public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
        {
            ...
            //How to get the parameters and pass to the Model?

        }
