Does anyone know what what's between the main lens and ultra wide lens?

What's that smaller circle? I know to the right of the camera bar is the telephoto, mic and flash, but what's between the wide and ultra wide lenses?

Probably the ambient light sensor. On the 6 Pro, it's next to the flash: https://www.reddit.com/r/GooglePixel/comments/r8ir97/fyi_pixel_6pro_has_two_ambient_light_sensors/
