Can grid maps be used to 3D place objects at run time, or are they an in-engine only feature?

Godot Version

Any

Question

I’m new to Godot and have been looking through the features just to see what’s available by default. I’m interested in the 3D grid maps feature, and am wondering if it’s usable at run time to allow the player to place objects in the game world, or if the feature only functions in the editor. Thanks!
