I want to wire these up to all 8 buttons in such a way that they simply turn on when pressed. As far as I’m aware, the simple way to wire it without a hex inverter was posted in the tutorial thread. Power to power and ground to the button’s signal. If so, would that mean that I would have to wire each button’s LED power to the VCC on the board? I’m not entirely sure how that is done. Solder directly ontop of the VCC? Cut the USB red wire and solder straight to it? Can I daisy chain all the power wires together if they are all going to one spot?

Or can I simply just wire ground to ground and power to signal here:
