o/PARASHOOT is operating as background service and as such is almost invisible. A symbol in the MacOS menu bar (top right) indicates that it is running.
NOTE: If you're on a MacBook Pro with a notch and can't find the app icon, it's most likely hidden behind it. You can either
Close other apps that have a lot of icons like iStat and then move the o/PARASHOOT icon while holding the ⌘ Command (or Cmd) key.
Use an app like Bartender to tidy up the menu bar.
