One technique I occasionally use is to look at the “zap” stanza of an app’s homebrew cask formula: https://github.com/Homebrew/homebrew-cask/blob/f44500902e420

One technique I occasionally use is to look at the “zap” stanza of an app’s homebrew cask formula: https://github.com/Homebrew/homebrew-cask/blob/f44500902e4207bb0ea8080225a7fbcd2c0db464/Casks/n/notion.rb https://github.com/Homebrew/homebrew-cask/blob/f44500902e420... Based on the “notion-updater” I’m guessing there’s also a launchagent/launchdaemon that is “updating” (read: reinstalling) it whenever you manually delete it.
