Both iOS (https://developer.apple.com/documentation/gamekit/connecting_players_with_their_friends_in_your_game) and Android (https://developers.google.com/games/services/common/concepts/friends) have Friends APIs. It would be great to add support for calling them.
This would allow apps to display the friends of the player and allow players to invite their friends to download the game.
