如何仅为反向动画GSAP设置timeScale

Question

我在这里尝试的是，当我切换 Bootstrap 按钮时，反向动画应该运行得更快，已经在 google 上搜索过 timeScale(3);，但是如何添加 timeScale 仅用于反向切换脚本上的动画。您可以检查示例

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());
});
