Please note that for the macOS target, you must have unchecked the "Start In Fullscreen" option and checked the "Allow the player to resize the game window" option in the Game Options, otherwise this function will fail. Also note that this function will not work on HTML5 unless add in as a "clickable" callback (see here for more details).
