How do I set text like demo? Promotion Headline

I am setting up with the theme "PhotoFocus Corporate" for my home page. I am unable to find an option to add header text only on the home page like on a demo site. https://catchthemes.com/demo/photofocus-corporate/ When I selected "home page/front page" on the Promotion Headline section under the customize, it will show all of the post. Please guide me how I do it.   Thank you
