I'm seeing a fbchess option. @fbchess help returns:

Make a move: use Standard Algebraic Notation @fbchess e4 or @fbchess Pe4 moves pawn to e4 Nbd2 to move knight from b-file to d2 B2xc5 to take on c5 with 2nd rank bishop e8=Q to promote pawn to queen 0-0-0 or O-O to castle

@fbchess play actually initiates a game including a picture of the active chess board within the chat window.
