Parse and Firebase Cloud Messaging with Sashi.do

I’m using Parse from Sashi.do for a cross-platform Xamarin.Forms (RIP) app.

Because Sashi.do itself is using modern Parse, I can target Android handsets for push messages and they’ll be delivered as FCM messages.

The catch is that I can’t then directly receive FCM messages because .NET Parse lacks classes like ParseFirebaseMessagingService.

…does anyone know how I should handle this?
