Hi Mads,
I coded it quickly for you:
<script>
window.laytheme.on("newpageshown", function(layoutObj, type, obj){
function showpanel() {
$("body").animate({ scrollTop: window.pageYOffset + $(window).height()}, 300);
}
setTimeout(showpanel, 2000)
});
</script>
Put it into the Custom <head> content section.
Here you can set the time in milliseconds: setTimeout(showpanel, 2000).
If you want to run it only on specific pages you have to change the page here:
window.laytheme.on("newpageshown", function(layoutObj, type, obj){
Have a look here:

I hope that helps!
Best!
