Ok, silly question, sorry. I've discovered I can add new custom inputs in input manager, didn't know it before.
Anyway method described by ChrisIceBox doesn't work. Interaction menu is displayed properly when player is on hotspot but I can't select…
AC is really brilliant, big respect for your work.
I did exactly as you wrote but I don't have CycleInteration and other inputs in Unity's Input Manager.
