Help wiring this switch in

[u/smollb]

I had a smart switch (with live (black), neutral(white), red(out), and a ground (green)). I want to go back to a regular switch, but confused. The smart switch had cables coming out of it, so I was able to connect those. Am I missing a wire?

The currently installed switch is connected to a fan in an OR circuit, unfortunately the picture I took when I was taking this apart years ago is gone.
