Fire TV Menu button

Curious about support for recently added functionality on Fire TV remote of being able to hold the menu button(just right of the home button) for app specific menus/functions. The Fire TV remote included with Simple Control has the menu button and it works fine, but it doesn’t seem to support the hold for 3 seconds and get a secondary behavior.

I would be very interested in the functionality to!!

Found it, it has been added as a separate command (Menu).
