What nav settings do I need to change to walk under this archway?

I tried adjusting the agent height and radius in the nav mesh settings, and also tried shrinking the character’s capsule.

What do I need to do to close this gap in the navigation? I’m walking under it crouched.

Solved for now by setting the top of the archway to only overlap with Pawn and Vehicle, but I’m still wondering about the nav settings.
