Programmatically access Legend Properties with JSL

I want to disable the default 'click-ability' feature of a legend. I can achieve this manually by selecting the legend properties (in a platform) and un-selecting the 'Enabled' checkbox. But how do I access these properties programmatically?

 

I tried making the change manually and subsequently 'saved script' using the RED triangle but it does not appear to record this property. 

Is it possible?

You can use gb << Show Tree Structure() to give idea of the elements and with that you can usually get idea how to access specific element

 

In this case you can access LegendBox this way:

gb_report = gb << Report; 
legend = gb_report[legendbox(1)];

and set property most likely with legend << Enabled(0)

 

Full example:

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
gb = dt << Graph Builder(
 Show Control Panel(0),
 Variables(X(:sex), Y(:height), Group X(:age)),
 Elements(Box Plot(X, Y, Legend(1)))
);

gb_report = gb << Report; 
legend = gb_report[legendbox(1)];
legend << Enabled(0);
