Hello Shruti,
Your website looks amazing!
Free version of the theme has some limitations. Premium version of the theme has some advance features. Just like this: https://prnt.sc/1b2la34
Here you can see there are two additional widgets. The Foodicious: Popular Posts widget is used in the Footer-top widget.
You can purchase the theme from the Download page: https://vinethemes.com/downloads/foodicious-food-blog-wordpress-theme/
Thanks & Regards
