How to mix "direct" keys and "matrix_pins" on the same keyboad in QMK. This is a Pico Sofle board with the 7 pins on a spare header. What to hook those 7 pins to "direct" buttons connected to a separate pin and ground combo.

Looked at

https://docs.qmk.fm/porting_your_keyboard_to_qmk#direct-pin-matrix

but can't figure out how to mix "matrix_pins" with a "direct". Tried several variations on

"matrix_pins": {
  "cols": ["GP1", "GP2", "GP3",   "GP4",  "GP5", "GP8"],
  "rows": ["GP9", "GP10", "GP11", "GP12", "GP13"],
  "direct": [
    ["GP28", "GP26", "GP21", "GP19","GP27", "GP22"],
    ["GP20", null,   null,   null,   null,  null]
  ]
},
