🤯 Is that so? Why do they have all those different modes to confuse a beginner like me? Thanks for the clarification!
cause they are different to some extent...
at least the Challenge one that is under "Play with Friends or Other Players" as i understand is different from invite and request, as it applies only to those users that already joined the game, for example a already existing user can invite his (non-players of the app) friends to play the game or challenge them to a match...
but he can't challenge a non-player of the app that isn't his friend... meaning he can't invite any random (that isn't his friend) person unless that random person already played the game.
to challenge a complete stranger you need the invite or request to join game module and only then u can challenge that player if he joined the app.
about invite and request to join a game/app they sound to be the same thing, unless there is some different hook but they probably will change that soon ...
