Display Shared Legend in Tiled Chart Layout - Example replication error message

I've just discovered the existence of tiledlayouts as an alternative to subplots and have been trying to recreate the "Display Shared Legend in Tiled Chart Layout" example on the legend documentation page here: https://uk.mathworks.com/help/matlab/ref/legend.html

tiledlayout(2,2);

nexttile

plot(rand(5))

nexttile

plot(rand(5))

nexttile

plot(rand(5))

lgd = legend;

lgd.Layout.Tile = 4;

It runs fine if I use the online "Try This Example" button, but when copied exactly into Matlab on my desktop (v2020a), I get the following error message:

Error in DataAnalysis (line 117)

lgd.Layout.Tile = 4;

Unrecognized method, property, or field 'Layout' for class 'matlab.graphics.illustration.Legend'.

This is infurianting as I understand what the error is telling me, but don't know why it's happening when I can see the layout property exists in the documentation here: https://uk.mathworks.com/help/matlab/ref/matlab.graphics.illustration.legend-properties.html

Would massively appreciate it if someone with better knowledge could explain this to me please. Is this a version issue or a package I'm missing?

Nevermind, it's something that was added in 2020b.

[Yiliang Wang]

right, it is only for 2020b.

When you say "only," do you mean that it's not in 2021a onwards?
