An array of

A text message to display to the challenged players.
This method should be used only to implement your own custom challenge user interface. You should only issue challenges when the local player directs you to do so.
If the achievement is marked as hidden in App Store Connect, or if the challenged player has already earned the achievement and it is not marked as replayable, then the challenge is not issued.
