Need help finding multiple feed reader for sidebar

I’m looking for an RSS news aggregator that will fit into the sidebar and pull in articles from multiple RSS feeds, that my client can easily update the URLs for in the WP back-end. Not something that requires inputting custom tags into the template, not something that only takes one feed, not something that syndicates a feed into posts.

Something that works the way the news aggregator does on this page:
https://www.drudgereport.com/ (on the left – it’s ugly, but it pulls in the titles for articles).

Is there a plugin that exists like this? The only ones I seem to be able to find are the ones I’m not looking for. Thank you for your help.
