filters – Adding link options in insert/edit link dialog window

Good afternoon! I am looking for a way to insert a text box inside this insert/edit link dialog window. Due to googles recent changes for rel/nofollow links, we would like to insert an option to add a ‘rel=sponsored’. However I can’t find any documentation that would allow me to do this. Is there a filter or action I can add to the core WP theme files that would allow me to edit the output of a link as well as add either a textbox or option to this dialog window?

thank you!
