Expedition differential fluid?

I bought a 2019 Expedition and noticed all suggested products for my vehicle listed here www.searchforparts.com/oil-change/ford-trucks-2019-expedition-3.5l-t-turbo includes gear lube for the differential?
is that necessary? I am very picky about generic fluids so I flushed everything out and replaced with those products but wondering what maintenance or actions to take with the differential, thank you.
