I have no idea how that person is doing it, but I suspect it could be using osascript. Here's how I do it from my homegrown Go bookmark tool:

  const fetchTabsScript = `
  tell application "Brave Browser"
      set output to ""
      repeat with w in windows
          repeat with t in tabs of w
              set output to output & (URL of t) & "|||" & (title of t) & "\n"
          end repeat
      end repeat
      return output
  end tell
  `  
  
  func GetOpenTabs() ([]Tab, error) {
   cmd := exec.Command("osascript", "-e", fetchTabsScript)
   output, err := cmd.Output()
    // ...
  }
