Since when getFacesMatId is available ?

Since when

polyop.getFacesMatId

is available ?
I just found it on Max 2023 I'm sure there was no such option in 2020.
What about 21, 22 ?
There is nothing in documentation about it, or I can't find it. It just there now :)
I glad it appaired, though, really useful. Makes things a bit easier :)

I will clarify that I'm not talking about getFaceMatID, but getFacesMatId.

A = getFaceSelection $ 

print (makeUniqueArray (polyop.getFacesMatId $ A as Array))
