How to use the toast.ToastMessage.from_address function in toast

print(f"Toast daemon already running or /dev/pex/{daemon} not closed properly.")
        sys.exit(1)

    os.environ['TOASTD'] = daemon
    pex_server = pex.PexServer(daemon)

    fds = [yutani.yutani_ctx,pex_server]
    while 1:
        # Poll for events.
        fd = fswait.fswait(fds,20 if sliding else 500)

        if fd == 1:
            size, packet = pex_server.listen()
            if size and packet.size:
                data = ctypes.addressof(packet) + pex.pex_packet.data.offset
                notification = Notification(toast.ToastMessage.from_address(data))
                notifications.append(notification)
        check_close()
        while yutani.yutani_ctx.query():
            msg = yutani.yutani_ctx.poll()
            if not yutani_mainloop.handle_event(msg):
                os.unlink('/dev/pex/'+daemon)
                sys.exit(0)
