AutoNotification Text Message Phone Number from Intercept

I'm using AutoNotification to intercept the notification from the Android Messages App and would like to capture the phone number of the sender. Typically the sender is in my phone book so the Title of the notification is the sender's name and not the phone number. I haven't been able to find the number in any of the other AN variables. Does anyone know if it is there and if so, where?

Update: I figured out how to accomplish the end result I was looking for by using the "Has Reply Action" switch and the "Reply" action of AutoNotification. No need to actually know the phone number. That makes it very easy.
