How to check PushNotifications for C# in Appium

I have tried


and it does not work in AppiumDotNetDriver. I contacted them through Github but no answer. I have also tried a little JavaScript

_driver.ExecuteScript(“mobile: getNotifications”);

The only other thought I have is trying to pull the shade and check for a Notification? Is that the recommendation if so is there a way I can ensure that I use it for multiple devices with multiple dimensions. Anyone know where to find some code for this?
