Filter out specific paths from Recents in macOS Finder

Arc generates a lot of JSON files remaining visible in the "Recents" folder in Finder, making it less usable.

It is possible to filter out specified paths to reduce noise in the Recents:

  1. Open System Settings → Siri & Spotlight → Spotlight Privacy...
  2. Add ~/Library/Mobile Documents/com~apple~CloudDocs/Arc App to the Privacy list.
  3. Click Done.

(I've added ~/Library/Mobile Documents/ since in my opinion, this folder is an ephemeral files dumpster that does not contain anything valuable in general.)
