Our game will soon be launched on Facebook(Gameroom and Webgame), and I have seen a sentence below, can you tell me what I should do with this? should I add a code? or can I set on developers' console without adding this code?
If your game is cross-platform and also available on Facebook Web, you need to detect and support the Gameroom client by detecting an additional user-agent string (e.g., FacebookCanvasDesktop [FBAN/GamesWindowsDesktopApp; FBAV/1.3.0.0]).
