I checked, it's not Reeder.
Don't know what it is either, but I'd like to got off-topic and remember with fondness the time when you could subscribe to RSS feeds directly in Safari. Google Reader was replacable, a direct integration into the browser not.
The RSS button is https://rssdiscovery.app/
And for a short time, RSS was the bee's knees across the entire Internet. Apple had the best support for it, and almost put NetNewsWire out to pasture, until they just removed all baked in RSS functionality, entirely :(
But I use Reeder across Mac, iPad, and iPhone to keep up with feeds.
