Cigarette Fuse

I have a 2018 Prius Prime. My cigarette plug inside the cabin (next to USB port) isn't working. Suspect fuse blown. I opened the black cover for the inside fuse box near the foot brake pedal. To my surprise, there was NO labeling of the fuses on the cover. Typically everything is labeled on there. The one in the engine does but not this one The manual doesn't show the diagram either. It just tells you where the two fuse boxes are located.

Anyone has a diagram for the inside fuse box or know which fuse(s) is for the cigarette lighter?
