configureCallback unrecognized function in R2019b

On this page:

https://www.mathworks.com/help/matlab/ref/tcpclient.configurecallback.html

it describes how to use configureCallback with a TCP/IP connection, and at the bottom it says that it was added in R2019b.

I installed 2019b and I find that I can display configureCallback in the help browser, but it does not have any of the TCP/IP related stuff, and on the TCP/IP help page it doesn't have anything about using configureCallback with it.

I get an error message that says "Unrecognized function or variable 'configureCallback' "

So my question is, what do I need to use this functionality? Do I need a toolbox? Do I need a newer version than R2019b?

configureCallback is a method build into some classes (rather than being a .m of its own.)

It looks to me as of configureCallback existed as a serialport method in R2019b timeframe, but that the tcp method was not added until R2020b -- notice that the UDP object page says R2020b.

I have my computer searching functions now for confirmation.

I confirm that up through R2020a, configureCallback is only for serialport objects (unless it exists in a toolbox that I cannot install on Mac such as Data Acquisition Toolbox, or is in a toolbox that I do not have, such as Automated Driving. I have a fair number of toolboxes, but even I have limits on how many I can spend meaningful time learning.)

Thanks! I asked my IT dept to install 2020b and I've confirmed that everything works as expected.
