How to use embedded touch sense controller (TS) on stm32L432kc?

I'm confused on how to use the embedded touch sense on stm32l432kc both as hardware and software. Concerning the hardware, It is written on the documentations that there is 3 capacitive sensing channels in group 2 analog IO in the stm32l432kc. What is meant exactly by group 2? and which pins correspond to group 2? And do I add the sampling capacitors and sensing capacitors or they're already embedded on the nucleo stm32l432kc board?

For the software part, if someone can please show me on Github an example project code that implement the touch controller
