Apple TV - Find Source Name - Node Red


I have setup the following integration to connect to my Apple TV. Via Node red i am able to get Apple TV to open NetFlix using the media source. Thats a pretty easy one to open.

However how do i find out what the correct source name is for other apps like Amazon Prime etc

inject node > current state (apple tv) > debug node (output

Under attributes should be the source. Change the source on the TV manually then run the above flow to see the current source
