Remapping Left click does not work on the trackpad

The code below doesn't work.

{
  "type": "basic",
  "from": {
    "pointing_button": "button1"
  },
  "to": [
    {
      "key_code": "a"
    }
  ]
}

My goal is to rebind ctrl click to command click but simply rebinding button1 isn't working at all. the rules from the import page that relates to rebinding ctrl click to disable it don't work either.

I'm on macOS mojave 10.14.6 using Karabiner Elements 12.9.0
