Using Google Maps for iOS on Xamarin Forms

Okay, I have this app that I need to render Google Maps on both iOS and Android. Xamarin.Forms.Maps renders its native maps based on the OS used by the device e.g. Google Maps for Android and MapKit for iOS which makes it easier for the Android to have Google Maps of course. What I want to achieve here is to also have Google Maps for iOS since the main map that we are using is Google Maps. How can I possibly be able to achieve this?

Thanks in advance.
