Copy absolute URL including div id on button click

In my site, every h2 tag is containing copy to clipboard icon, so when I hit the copy icon button, the URL should copy including div id.

Example, the absolute URL is “mysite dot com” and the div id is “process-invoices” so when I click on the copy button then the url should copy like this “mysite.com/#process-invoices”

<div class="wrapper" id="process-invoices">
  <h1>Process invoices</h1>
  <button onclick="copy absolute url with above div id value">Copy to Clipboard</button>
</div>
