How to import and implement a 2d Wonderdraft map for a pawn based world navigation system? (similar to pillars of eternity 2)

So, in our game we would like to use a world navigation system that is very similar to Pillars of Eternity 2: to from A to B you are a small pawn, and you click where you want to go, very simple and basic. To do this I created a very detailed map using the program Wonderdraft, however how-on-earth do I import and implement it in my project? I’m surprised I dind’t find any hints about this, am I the only one using this navigation system?
