No because we can’t ask the system what your default application is. In theory we could ask the system whether an app is present that handles the fantastical2:// url and then call it, but I’m hesitant to do so as a) the user might have fantastical installed but is not really using it and prefers the calendar app or b) there might be other apps on the system that support this url scheme without being Fantastical itself.
