POWER SW & PLED Connection Locations on LP3Δ?

I bought a chassis switch hoping to be able to connect it on my LattePanda 3 Delta.

It is a push button switch. There are 4 cables with female pins that extend out from the button switch itself.

Two cables (yellow and white) are joined together labeled "POWER SW".
One purple cable is labeled POWER LED -.
Another white cable is labeled POWER LED+.

Can anyone help me figure out where on the LP3Δ do the cables go? I can solder if necessary.

Thanks!
