Blender GLTF and Shadows

How do I generate a shadow from a light in a GLTF? I’ve exported from Blender a GLTF, I see in the scene explorer “Spot” but don’t get a shadow.

(from the inspector I can click on shadow generator for the light and then get the shadow, just haven’t figured out what that does exactly)

Thanks for the help, have spent a couple days getting frustrated over this!

You have to create a shadow generator to add shadows to your scene.
