Custom button click to a specific slide?

hey guy. I have three slides. I want to add a button inside the second slide that would take a user to the last third slide. do you know how I could do it?

I found some article from @bartekkustra here with the following code:

$(document).ready(function() {
// gotoslide1
$(‘#gotoslide1’).click(function(e) {

But I am not sure which class to attach to the button itself so that this specific button was triggering the code.

or maybe there is more simple solution?

thank you
