How do I access to CKeditor Image resizer web element in menu pop up?

Image resizer CK editor

I need to get a way to obtain the html web element tag and attributes of the menu popup options to resize the image. But when I Inspect the element it does not select any html element, I only can acces to the image, not to the option items of the popup menu to resize it.

Inspection of html

So can you help me with this?

This is the page where I am obtaining this example: https://ckeditor.com/docs/ckeditor5/latest/features/images/images-resizing.html

Thanks in advance
