Yii2 Simplechat

Did anyone try and manage to work this extension:


I’m trying to figure out what I need to do if I want to use this without twig. So far, all i have done is installing via composer. I am not sure do i need to make my own views since this ones are twig, or what i need to change in my app config. If there is anybody who managed this to work, can you please help me with some basic instructions?
