How to Make Scrollbar Custom Arrows Work On Mobile Devices

Question

I want to show horizontal arrow buttons that disappear when the container is not scrollable. I used the answer here. It works on PC but not on mobile.

How do I make it scroll on mobile devices when clicked?

My needs are:

I want it to scroll on mobile when clicking the arrows.
I want the arrow button to auto show when the overflow is active.

// Show gradient and left/right arrows only if scrollable
$(".scroll-area").each((i, el) => {
  $(el).parent().find(".right")[el.scrollWidth > el.clientWidth ? "show" : "hide"]();
});

// Show/hide gradient and arrows on scroll
$('.scroll-area').scroll((e) => {
  const fullWidth = $(e.target)[0].scrollWidth - $(e.target)[0].offsetWidth - 1;
  const left = $(e.target).scrollLeft()

  $(e.target).parent().find(".left, .left-arrow")[left > 0 ? "show" : "hide"]();
  $(e.target).parent().find(".right, .right-arrow")[left < fullWidth ? "show" : "hide"]();
});

// Scroll on left/right arrow mouse down
let intervalId;
$(".left-arrow, .right-arrow").on("mousedown", (e) => {
  const scroll = $(e.target).closest(".sc-head-menu-wrap").find(".scroll-area");
  intervalId = setInterval(() => {
    const left = scroll.scrollLeft();
    scroll.scrollLeft(e.target.classList.contains("left-arrow") ? left - 10 : left + 10);
  }, 50);
}).on("mouseup mouseleave", () => {
  clearInterval(intervalId);
});
