What, if any, integrations exist "out of the box" for Play Games services? For example, if we try to show an achievement or a leaderboard while in Daydream, what happens? I assume something terrible happens - such as trying to show regular 2D UI. Or maybe nothing. Or maybe ... just maybe ... something appropriate for Daydream happens? For that matter, even the default UI for showing the login is concerning - will that try to show inappropriate 2D UI while in Daydream if we use the new seamless Play Games login? Thanks!
