How to make smooth anchor scroll for safari ios?

Question

safari

The css has the property scroll-behavior: smoth; , which does not work in some browsers, including safari on ios.
I found the only option on the net - the smoothscroll.js polyfill. The option is either difficult, or I do not have enough experience / skill to put it.
Are there alternatives? Or maybe an instruction in Russian for installing a polyfill? I would be glad for any help :)

Answer 1

smoothscroll.js, translating the documentation
Add before the closing body

<script src="path/to/smooth-scroll.polyfills.min.js"></script>

or
CDN in the header

<script src="https://cdn.jsdelivr.net/gh/cferdinandi/smooth-scroll/dist/smooth-scroll.polyfills.min.js"></script>

Create a link and an anchor (go any)

<a data-scroll href="#bazinga">Anchor Link</a>
...
<div id="bazinga">Bazinga!</div>

Also below

<script>
  var scroll = new SmoothScroll('a[href*="#"]');
</script>

Can you adjust the speed

var scroll = new SmoothScroll('a[href*="#"]', {
  speed: 300
});

Everything is clear in the doc
