Which pins are used on the New RPI PoE hat 6 pin header?


Which pins are actually active on the 6 pin header of the New PoE hat?

I want to use the PoE hat on a raspberry pi 4 with a Pimoroni LED Shim https://pinout.xyz/pinout/led_shim
which needs GPIO 2 and GPIO 3 (for I2C) as well as 5V.

Is the 6 pin header on the PoE hat only connected to 5V and GND? Or is it using the 3V3 and GPIO 2&3 as well?
