I saw touch2-5 touch7-9 on the layout image. not quite sure how to use them

There are examples in Arduino esp. Just write the code and touch the IO port after running. You will see the response. https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Touch

In the original code, there are 2 Button 2 instances attached to pins 35 and 0, but these pins are not on the board. How or where should I connect to these pins?

For those who will stumble upon this question.

GPIO 0 and 35 are physical buttons that have to be clicked, TOUCH GPIOs are supposed to be, well, touched. Change of voltage upon touching gpio with a finger on the pin gets detected.
