Navmesh Rotation Problem

I made an enemy out of blender, and imported it to Unity.
I set up the navmesh so that the enemy follows the player, but the enemy is sideways.
Is there anyway to make the enemy face forward while using navmesh or changing the rotation in Blender?
The problem with rotating it in Blender is that when you put it in Unity, it automatically corrects the rotation, it thinks it's supposed to be the wrong way.
How can I fix this?
Supposed to face this way(forward): But comes to me this way(sideways):
