Pathfinding in a top down game

Hey,
I’ve been working on a top down squad game for sometime and decided it was time to improve the pathfinding.

Here’s what it’s currently doing:
Current RPG Pathfinding

I’ve never done anything with this in the UE before and I’ve found guides but most are for grid based pathfinding and not open world.

Can anyone link me guides, tutorials that would imrpove it in this style of game?
