Is it possible to access '::after' piece of code from the HTML?

In the image, when I am hovering my cursor on ::after only then the plus icon gets detected/highlighted.
But when I right click on ::after it does not give the option to copy the selector or xpath.

Is there a way to access this ::after?

Read this first.

In CSS, ::after creates a pseudo-element that is the last child of the selected element. It is often used to add cosmetic content to an element with the content property. It is inline by default.

::after is not a HTML element. It is not an accessible entity at all. There is no XPath for ::after defined.
