Help with CodeIgniter 4.0.4 Debugging in VS Code

Hello,

Am new to PHP and from NodeJS dev. I would like to know how to set up debugging PHP especially CodeIgniter in VS Code.
I Installed PHP latest and CodeIGniter latest and created appStarter project and able to serve using "php spark serve" in port 9000. I would like to set break points and run the code igniter project and debug it. I explored so many SO posts and Xdebug, PHP Debug but non helped.

Any help or guidence much appreciated. Thank you.
