What is the Google Chrome extension for reading RSS when closed?

Question

Google Chrome

Good afternoon, I'm looking for an extension that would allow popaping a certain window using Google Chrome even when closed.
That is, let's say I'm subscribed to 5 RSS feeds, and I want this extension to poll them every 5 minutes, and if new ones appear, it would display a window in the corner of the screen, showing the titles of the latter. But it displayed them even in a closed browser (provided that in the browser settings, of course, there is a check mark for the browser to work in the background)
