How to edit navigation between posts?

Hello,

When I view a page with a single post, there is navigation between them below it. That’s correct, but it only shows “Next/Previous Post“. However, I needed to create an identical visual on another site and I noticed that it only shows “Next/Previous” and the name of the post below it. I personally like this visual better, but I can’t figure out where exactly to set it.

Please help

Thank you
