Add static mesh component basic shapes?

Hi I’m using the ‘add static mesh component’ inside a construction script of a blueprint class.
Now it seems I can only choose from the static meshes that are inside my content folder, but what about the basic shapes like sphere and cube?
Any idea how I can add these as component in bluescript? thanks!

Enable Show Engine Content in the view options of the drop down menu you pick the mesh from and you’ll be able to find those basic shapes.
