Google Assistant Input_Button

I was wondering if somehow the new Input_button could be added to the Google Assistant exposed domains. I would think it would be very similar to the boolean but it is always off.

Did you ever figure this out? I see it’s supported in the documentation, but they aren’t showing up in my devices.

I just figured this out from another thread. Buttons are created as scenes that can be triggered by a routine, there doesn’t seem to be any option to manually trigger them from within the GH app or without adding a routine to call them by voice.
