PCG does not work in UE 5.5.4

Hello there!

I have created a new top down project in UE 5.5.4 and added a PCG plugin and…it does not work.

I repeated the same steps from tutorial: Procedural Content Generation Overview | Unreal Engine 5.5 Documentation | Epic Developer Community
After Create a Simple Forest Volume and it just does not work.

Could someone help me or explain me what happening?
