Signal Analyzer - Unable to view Complex Signal

I am trying to view complex signals in the signal analyzer app as is done in this example: https://uk.mathworks.com/help/signal/ug/visualize-complex-signals.html
However, even when I copy this exact code the complex envelope is not available in the workspace browser. I have Matlab 2019b installed and unfortunately I cannot upgrade with my student license. Could this be the issue, that I do not have the latest version?
Code:
fs = 2e3;
t = (0:1/fs:1-1/fs)';
inph = sin(2*pi*19*t);
quad = chirp(t-0.6,61,t(end),603,'quadratic');
env = inph + 1j*quad;
g = timetable(env,'SampleRate',fs);

I am not sure that I understand the problem. The ‘env’ and ‘g’ variables appear in my Workspace (in R2020b).
There are several Bug Reports for Signal Analyzer in the Signal Processing Toolbox for R2019b, specifically Bugs Existing in R2019b. The remedy for all of them appears to be to get all the Updates to R2019b. I suggest you get the Updates.
Previously, ‘Check for Updates’ was in the Add-Ons, then it changed to Help, although I don’t remember exactly when that was. Check both of them, download and install the Updates, and that may solve your problem. In any event, it will present future problems that the Updates fix.
