How to use

First step is plugin initialization

var play_games_services
# Check if plugin was added to the project
if Engine.has_singleton("PlayGameServices"):
  play_games_services = Engine.get_singleton("PlayGameServices")
	
  # Initialize plugin by calling init method and passing to it get_instance_id() and a boolean to enable/disable displaying game pop-ups
  
  var show_popups := true # For example, your game can display a “Welcome back” or an “Achievements unlocked” pop-up. true for enabling it.
  var enable_save_games := true # If you want to enable Saved Games functionality. true for enabling it. If enabled, it will require additional Google Drive API permission from the user.
  play_games_services.init(get_instance_id(), show_popups, enable_save_games)
