How to show WP RSS feed to an HTML website?

Let’s say I have a website homepage https://example.com/index.html (regular html. no PHP fancy or anything like that)

Amd I have a WP blog at https://example.com/blog

Now I want to have the RSS feed from the blog posts to show up on a small section in the homepage (index.html) in a widget-like. Similar to Twitter feed or Facebook widget feed that we often see on websites these days.

Does WP have a widget to do that? If not, what’s the solution(s)?
