How do I make a hggroup show up in the plotbrowser?

hg = hggroup;
hg.Annotation.LegendInformation.IconDisplayStyle='on';
hg.DisplayName='my data';
h=plot3(randn(5,5),randn(5,5),randn(5,5),'Parent',hg);
plotbrowser('show')

The code above does not work. I'd like to have a single entry in the plotbrowser for my datapoints.

BTW:

legend('show')

shows a single legend entry as intended.

yes exactly, I'm talking about the right hand side panel. I want to be able do toggle the visibility of all lines of a hggroup with one checkbox on that right hand side panel.

Just for reference, that's what I came up almost 8y ago: Create an invisible dummy which represents the hggroup

clf, plotbrowser on
hg = hggroup;
h1 = plot3([0 1],[0 0],[1 1], 'parent', hg); 
hold on
h2 = plot3([0 1],[1 1],[1 1], 'parent', hg);
ax = ancestor(hg, 'axes');
hDummy = copyobj(h1, ax);
drawnow;
hDummy.DisplayName = "my group";
hDummy.Annotation.LegendInformation.IconDisplayStyle = 'off';
lp = linkprop([hg hDummy], 'Visible');

Caveats

plotbrowser must be called before dummy creation
drawnow is needed, otherwise the dummy is not shown in the plotbrowser
a reference to the linkprop object needs to be kept in memory. A good location is in the UserData of the graphic object itself. Furthermore, linkprop() has (or at least used to have) a significant performance impact, which can be worked around with a custom stripped down linkprop()

All in all very hacky. I stumbled upon my own post again since I'm looking for a plot browser solution for the new web based uiaxes(). plotbrowser() only works with the old java based figure.
