The Public Links & Redirects page provides a list of each web component, for the selected website domain, with the version of the component (Legacy or Latest), the URL, and a Copy URL button to copy that link if you need to send it out or apply it to a webpage.
If you have a component where the version shows as Legacy then there will be an Upgrade All Pages button at the top. Please refer to this article as there are things to do before you upgrade.
