I would like to include/positioning a button in the header of a webpage.
It would be helpful if you could tell me how I can place a button in the header. When I tried to position that button in the header, it does not overlap it.

It is unclear what you mean by your request to add "a button in the header of a webpage". In this example, I added a button at the very top of the page. The button is set to position:absolute so it will overlap other content as you requested. (If this doesn't work, add button.style.zIndex = 999; to the code.)
const button = document.createElement('button');
button.textContent = "I am a button!";
button.style.position = 'absolute';
button.addEventListener('click', ev => {
// randomly change the button's text color when it is clicked
button.style.color = "#" + (Math.round(Math.random()*2**24)).toString(16)
});
document.body.insertBefore(button, document.body.firstChild);
<p>This is a <em>very</em> simple HTML body.</p>

If you want to insert it into a menu at the top of a page, you'll have to figure out which DOM element to add it to. You'll probably want to clone its style as well. I can help further if you specify the website and where you want your button. If you can't share the whole site (e.g. it requires a login or a VPN), you can paste a snippet (barring legal hurdles; keep it short to qualify for copyright fair use).
If you're adding the button to a dynamically-added parent, you'll need to wait for it to be loaded.
