ESD protection for external button(human touch activated)?

Hello,

In my next project I plan to conductive pads as buttons(that are exposed for humen touch to interacte with the) one is connected to ground and the rest will connect directly to the nrf52832 chip with an internal pullup resistor.

Now the question is how safe this setup would be against ESD as there will be a direct contact with the man and the pad?

also my other concern is if two input pads would short out accidentally would any damage be caused to the chip? if so what could be a solution for it? tested this one with arduino and it didn't seem to do much but maybe it's different for that one.

Thanks for your time!
