How to add Nav Link to Nav Menu List Item

I am working in the Doctor X template and would like to add a Nav Link to some of the Nav Menu List Items that do not currently have a link nested. Some of the items on the nav dropdown are Nav Links nested in a Nav Menu List Item and some are only Nav menu list items. I assume there is an easy way to add and remove Nav Menu List Items as well as Nesting links inside them but I have been searching for days and I can’t figure this out. Please help. Thank you
