Two External Displays Mirroring Each Other

I have connected two external displays to my MacBook Pro (16 inch, 2019). I would to extend my desktop but have the two external displays mirror each other. I want to display things on my Retina display that only I can see while having viewers of the external displays seeing the same thing.

In System Preferences > Displays > Arrangement tab, set up the three displays as an extended desktop, and then Option-drag one external display icon onto the other external display icon to mirror the two external displays.
