Set up a simple button in canvas in a game scene and call it anything. We prefer “Send game invites”
And that's it!
You can now easily send game invites!
After you login and click the send game invites button, you’ll be presented with the following screen to select a game.
In this screen, click any of the select buttons to select a game. The invites will be sent for this game.
When you press select, you'll be presented with the following screen, i.e. your friends.
Once you have selected your friends by pressing the select button, tap the send invites button at the bottom. And when the invites are sent, you’ll be presented with a screen that tells you that invites have been sent!
