Four-finger swipe for backlight?

[PerpetualCreativity]

Is it possible to adjust the keyboard backlight using a four-finger swipe? Analogous to two-finger swipe for volume and three-finger swipe for brightness. I tried the following:

{
    "type": "swipe",
    "fingers": 4,
    "direction": "right",
    "action": "hidKey",
    "keycode": 21
  },
  {
    "type": "swipe",
    "fingers": 4,
    "direction": "left",
    "action": "hidKey",
    "keycode": 22
  },

in items.json, but it didn't work...

I think your idea is great, but... In my view that swipe use four fingers on such a narrow TouchBar is hard...

'Four finger swipe' is already an option for custom sliders. I am asking whether it is possible to treat keyboard backlight like a slider as well.

I would love that too. But it seems to be very hard to change keyboard illumination programmatically by scripts.
