How to set timeScale for only reverse animation GSAP

Question

What I'm trying here is when I toggle the Bootstrap button then reverse animation should go faster already google about timeScale(3); but How can I add timeScale only for reverse animation on toggle script. You can check Example

gsap.set("#sidebar-nav a", { opacity: 0, y: 100 });
var nv = gsap.timeline({ paused: true })
 .to("#sidebar-nav a:nth-child(1)", { duration: 0.2, delay: 0.3, opacity: 1, y: 0 })
 .to("#sidebar-nav a:nth-child(2)", { duration: 0.2, opacity: 1, y: 0 })
 .to("#sidebar-nav a:nth-child(3)", { duration: 0.2, opacity: 1, y: 0 })
 .reverse();
 
var buttOn = document.querySelector(".toggle-btn");
buttOn.addEventListener("click", function() {
    nv.reversed(!nv.reversed());
});
