Top down 3D with cubes, AI travel between cubes question

1

Hi there!
I was wondering if this can be done with your asset:
A top down 3D game of cubes 1x1 unity units where the AI has to walk between gaps of 1x1. The AI has a radius of 0.25.

In the first image I placed cubes with 0.9 on collider with a grid graph, but then the AI hits the edges as he is walking through the door

Here I tried offsetting the grid by 0.5, but then the AI can only travel at gaps of 2x2 cubes

Thank you.
