Try the setTimeout method:

setTimeout(function(){
     // Code here will run after the timeout 
}, 15000);  // Time in milliseconds

It didn't work, here is my code below.

const myButton = document.getElementById('start');

start.addEventListener('click', () => { setTimeout(function(){ alert("hello"); }, 15000); // Time in milliseconds });
