Add patrol to a navmesh script

Hello, i have baked navmesh, enemy with navmesh agent script that detects player from certain distance and follow it.
If enemy doesn't see player = stay on one place

When add patrol script with waypoints, so enemy partol with these waypoints when he doesn't see player, (but when navmesh agent script is ON), the enemy doesn't use partol waypoints and again just stays.

What i have to add to the navmesh agent script, so it knows about patrolling script? (First Patrol, if player is in range - use navmesh script, when player is out of range - use again patrol.
