We're looking at moving to Lightning and need to update some of our visualforce pages. I love how easy it is to add the attribute lightningStyleSheets="true" to style a page for lightning. The only hitch is that we have two visual force pages. One contains a few different items including a button to the second page. When users click this button they're redirected to the second page but they're missing the Lightning Navigation bar. How do I get this back?  #LEX4VF
