There are examples in Arduino esp. Just write the code and touch the IO port after running. You will see the response.

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.
