Add Existing wordpress.com blog to my website

Hi: I have a wordpress.com blog https://www.lisajeydavis.wordpress.com. I would like to integrate it into my website which now utilizes wp programming and has a theme, as well as a “blog” page https://www.lisajeydavis.com/blog. How do I do this? I don’t see any posts on what to do to upload or integrate the .com blog into my existing site?
