My '21 have them. The steps are called Multipro steps, to go along with the Multipro tailgate theme.
I don't know if'n they are available on the AT4 or if it's just the Denali's. Never looked into it.
ETA...the steps can be controlled by a piano key on the dash also. Allows one to extend the steps out from the seat. Nice at truck washes.
