On this page: https://developer.apple.com/documentation/tvservices/tvtopshelfaction it states: "When configuring items for a carousel interface, you can specify a custom title and image for the buttons in that interface. If you do not specify a custom title and image, the system chooses default values based on whether you assigned the action object to the playAction or displayAction property of your item."
However, I cannot find anywhere in the documentation where you can actually set a custom button title and image.
I notice the built-in TV app has custom Play button text.
Any ideas?
