Will Tabletop Simulator run on the Steam Deck

Why Tabletop Simulator doesn't work on Valve Steam Deck
Valve gives the reason "SteamOS does not support this game" (test code SteamOSDoesNotSupport) without further details; by Valve's definition, Unsupported means the game does not function on the device.
| Device | Valve status |
|---|---|
| Steam Deck | Unsupported |
| Steam Machine | Unsupported |
| SteamOS (other devices) | Unsupported |
Valve statuses are independent per device: the Steam Machine is more powerful than the Steam Deck, and "SteamOS" covers other devices running that system.
