Where do i edit navmesh data so AI goes around walls and corners?

So i have an AI tank that has a floating pawn movement component to move in a navigation mesh. It gets stuck behind walls while moving. I might have to adjust agent properties. Now i found 4 places where i can change all that and i’m confused about the differences. I’ll sum them up.

Project settings → navigation mesh

Project settings → navigation system

aiTank → floating pawn movement component

recast navmesh in the level

What is the difference between all them?
