Where's displayWaveformLabels method documentation?

I'm working on heart sound segmentation and I've found this new tutorial for R2018b.

https://www.mathworks.com/help/signal/examples/waveform-segmentation-using-deep-learning.html

I cannot find documentation regarding certain functions, such as displayWaveformlabels.

patientID = 1;
signalVals = getSignal(QTData,patientID);
labelVals = getLabelValues(QTData,patientID,'WaveformLabels_Chan1');

displayWaveformLabels(signalVals(1,1:1000),labelVals.Value(1:1000)) 

Does anyone know about this?

Thanks a ton

There is no documentation for it. There is just the very small bit of help information from inside the file itself.

The function exists only as part of the one example. It is not on the MATLAB path normally. When openExample() is used with the proper example name, the function is copied onto your MATLAB path.
