WYSIWYG editor: How to activate the title and the target to create a link

By using Drupal 8, with the link icon in the wysiwyg editor, currently in the modal popup window, it only allows the URL. I need to go to the source to add title and target attributes (outside of the website). Is there a way to add these fields in the interface especially this modal pop-up? Looks like it's CKEditor. My client is not as expert in HTML.

Let me know + steps to allow … thanks, any help would be appreciated.
