Add meta description to home page

Site URL :https://www.xilanchem.com

I need to add meta description to my home page, which is “products”

I am using Yoast plugin to seo. even thought I could add the meta description to products page it does not appear. other pages do not have such a issue. I like to mention that I am using product page as a blog post page and front page and home page are different

Thanks in advance
