My RUN and DEBUG doesn’t appear in vs code Help, I use xampp

I think there was supposed to be a green arrow that says run n rebug but mind just didnt exist, or maybe someone can teach me how to debug in php with xampp

I have PHP DEBUG by xdebug.org installed
I followed this video, https://www.youtube.com/watch?v=8ka_Efpl21Y

I ran my xampp, put a break point in a function where the code is supposed to run,

I open my website by typing the localhost url in chrome,

fill in my form, the website works, but nothing happens from breakpoint.

I saw people on YouTube have something called a run n debug but mine just doesn’t appear. When I press ctrl + shift + D, there’s checkbox for NOTICES, WARNINGS, ERRORS, EXCEPTIONS, EVERYTHING, but green arrow button with run n debug like I saw on YouTube
