Part numbers for chrome trim, possibly rocker panel/molding, for color change?

I apologize in advance because not sure what it’s called but the chrome trim piece that is at the bottom of the doors ( rocker panel/molding maybe? )…. Does that have its own part numbers or is it part of the panel itself? Wife just picked up a 23 limited and had a nightshade before and prefers the black chrome instead of chrome.
Not sure if anyone had a nightshade that did front rear or side mods and has pieces left over and wants to get rid of.
TIA
