How to connect my BP_Button component with level?

I have level with NavMeshBoundsVolume component, also level including my custom BP_Button for spawing AI.

In BP_Button there is a simple butotn for spawn AI Enemy.

My question is, how to get NavMeshBoundsVolume from level (parent BP) and on button press get random location in NavMeshBoundsVolume component for AI Enemy spawn. I dont know how to link NavMeshBoundsVolume to my BP_Button.

Thank you!

But it will only work if the level is open.
