[help]How to map capslock + w to "delete"?

[Bug-terminator]

I modified the configration, but it works like "screenshot"(When I press capslock + w, the screen will flicker). Here is my configeration, please correct it, thanks!

          "from": {
            // "key_code": "delete_or_backspace",
            "key_code": "w",
            "modifiers": {
              "mandatory": [
                "right_command",
                "right_control",
                "right_shift",
                "right_option"
              ]
            }
          },
          "to": [
            {
              "key_code": "delete_or_backspace"
              // "modifiers": ["left_command"]
            }
          ],
          "type": "basic"
        },
