How do I make my enemy character walk from one point to another and despawn?

This is a layout of the area where I have an enemy that uses a behavior tree to walk around and it works well.

The red arrow in the second picture shows what I want where the enemy walks past the player (green arrow) and despawns at the red x just to give the player the creeps for a while until the chase sequence starts (which I already have working).

The third picture shows how I’m using my own enemy controller.

What I did was I removed the enemyController so it wouldn’t search for the player and instead just walk from one point to another and then destroy itself. I don’t know how to get it to move and walk even when using the nodes to say to walk to a location.
