Hi,
i have no idea how i can put these interesting button (see picture) to my remote3. a app-switcher ON the remote3.
because there is no availability within the key assignment?
i use the “apple tv integration” from unfolded circle.
you can see this button if go to the “used devices” area within your active activity on your remote3.
hopefully someone can help me. 
thanks!
You must create an activity, add TV and Apple TV entities. Now you must create button mapping as you like and create a GUI with what you like. Starting certain Apps from the GUI works with the input source command. Before you ask no you cannot get the app selector from your pictures in the GUI of an activity.

You can’t add this button to activities but you can use the input source command and choose the app from the dropdown to create a widget or button mapping that opens a specific app.
It’s a pitty but thank you for the hint with the input command!!
