How to enable webSocket in codeigniter 4?

Im still very new and interested in developing a web system with Ratchet webSocket. Any tutorials to learn?

PHP.INI:
If you use a library you should copy it into the app/Library folder and set it up.

Code:

;extension=sockets

// Remove the ; semi-colon.
extension=sockets

What did you Try? What did you Get? What did you Expect?
