Create IA actor in custom viewport

Hi, I am creating a tool in a custom viewport, but i have a problem with a simple AI. I am trying to move an actor with the node “Move To Location or Actor” but it doesn’t move. i have add a NavMeshBoundsVolume scaled to be sure that the AI is inside the NavMesh, and i also add a ground but it still doesn’t move. Is someone have some advices to help me with that problem? (In blueprint please)
I Include a video who show the Blueprint works in game but he deosn’t in my tool.
