Help solve this problem with the 11ty blog page and _site blog problem

I was developing a site with 11ty with Netlify CMS. I wanted it to come out with the CMS, and when I uploaded any blog through it, it would go to my all-articles folder and then when I ran the npm start command, it should output the .md file as a .html file in the _site directory.

So, I had done most of this. But, whenever I create a new blog post, it doesn’t convert to html in the _site directory and doesn’t update the blog page to show the new blog.

Please do kindly point out what mistake I had done and it will be much appreciated. Thank you.
