Need location of oxygen sensor

My engine light came on and I went to a automotive electrician and P00551 code came on. So I need to replace my 02 oxygen sensor Bank 2 Sensor 1. I bought the part thinking it would be easy to spot but after looking around I can’t seem to locate it. Do I need to go from the bottom or top? Does anyone have a diagram, or location of it?
