Scroll DOM Element from a non-scrollable element

I've made a small Codepen clarify my problem: https://codepen.io/valentin-wei/pen/YzZNOKW I want to scroll the inner paragraph when I scroll anywhere on the page even on the non-scrollable div.pageContent.

So what I need is something like

domElement.scrollTop += x

However, it seems that "x" is different depending on the used browser or mouse settings. Note: I don't want to use jquery.

Is there any way to implement this behavior so the user has a "native" scrolling experience?

The expression when I scroll anywhere on the page probably means when you send a trigger that can lead to a scroll, like a wheel event. If that is the case, you can just use the dy property of the wheel event:

let el = document.querySelector('p');
window.addEventListener('wheel', function(e){
  let dy = e.deltaY;
  el.scrollTop += dy;
});
* {
  padding: 0;
  margin: 0;
}

.pageContent {
  width: 100%;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.pageContent > p {
  height: 200px;
  width: 200px;
  overflow-x: hidden;
}
<div class="pageContent">
    <p>
