hs.notify.show doesn't work

[x-tropy]

hs.hotkey.bind({ "cmd", "shift", "ctrl" }, "J", function()
  -- hs.notify.new({ title = "Hammerspoon", informativeText = "Hello World" }):send()
  print("Hello World")
  hs.notify.show("title", "subTitle", "information")
end)

The console prints "Hello World", but notification is not generated. And the commented line also doesn't work.
