Adding Aux Trailer Backup Camera

Has anyone been able to add the wireless backup camera to a truck that didn't ship with it? I have seen some discussions on various Tacoma forums where people say they found information about the Tundra having it and partial parts lists, but I can't find any other information. It seems like there might be an additional ECU, definitely some additional roof antennas, needed, plus some programming.
The AllData information available for the 2022+ doesn't seems to mention it at all according to my local mechanic and the dealer I got the truck from says they don't know anything about it either.
