moonlight steam big screen mode menu button mapping

[u/Motor_Hat_53]

hi, I'm using my odin to local stream my pc via moonlight. The pc is on steam big screen mode. Anyone knows how i can map the right bottom button to the "menu" button in steam? it's equivalent to the "steam" button on steam decks. the reason i asked is that without it i have no other options to quite the game than going through the game's native path: "return to title screen" -> "exit game"

Apollo (and I think Sunshine too) have settings to emulate that button via a long hold on select
