I don't have a shader Gizmo primitive in my list that I can see. Am I missing an add-on or is it just a custom model? I can't help but feel like I've seen it before, but I'm just going to assume it's a custom model for now.
I think you have to upgrade to pro subscription and you can download the gizmo file.

The Gizmo isn't a primitive in Blender's "Add" menu - It's just a model that you can open with Blender and it's available for download to subscription members, as antimatter said.
