Hello, I want to resize my game to be the exact same size like the browser window, and if the window resizez, the game will resize too and the text aswell.  
Anyway, to do that I need the ScaleManage, but it does not work for me, the error I get in the console is:  
TypeError: Phaser.Scale is undefined  
Everywhere it says is that because you need version 3.16 but I have version 3.55, and reinstalled it twice.
