I haven't played the game but support will be added when the game is launched next month. In the meantime I recommend loading XIM with various game configs then setting a config cycle key until you've found one with the best fit. Next assign buttons based on the button name in Manager and what that button does in game. Do not assign buttons based on the action names listed in Manager as they will be incorrect for your game.
Hopefully someone playing the beta can share their settings as well.
