Amazon Subscription Deep Link

I have an AIR app that is a subscription app.  Inside the app, I have a button titled "Change Subscription".  When you click it, I want the app to open the subscriptions within Amazon AppStore.  I have gotten this to work on both iOS and Android, but I can't find the deep link to subscriptions for Amazon Fire devices.

Does anyone know the Deep Link to Amazon Subscriptions for Fire Devices???
