Photoshop 3D, Secondary mini view missing

Hello, 

I'm giving a try to the 3D tools available in Photoshop. I am using Photoshop 2019 and 2020 and for some reason, the little window that gives as an additional view and can usually be found on the top left corner in most of the tutorials I am following is missing in my Photoshop.

I wonder how can I activate it, and deactivate it.

This is my view

And this is the view I am missing.

Thank you.
