To change Scrolling Block Speed, you can follow these.
#1. Edit Scrolling Block
#2. Click Design > Choose 0.5x or 1x or 2x
#3. If you want to use other options (4x, 5x…) you can use this code to Page Header Injection (or Code Injection Footer)
<script type="text/javascript">
// this will only find the first marquee on the page
// (at the point that the script is executed)
const el = document.querySelector(".Marquee-props")
const props = JSON.parse(el.innerText)
props.animationSpeed = 5.0 // this is the speed!!!
el.innerText = JSON.stringify(props);
</script>
