Custom Package node_label show ArrayList values

Hello,

I would like to ask if someone knows if it is possible to display on node_label the values set on an ArrayList on the “@CommandPkg action”.

So, it is possible to show String values from variables, but I didn’t find a way to show the values of an array (concatenated on a string using for example Arrays.toString(array). Check the screenshot if may also help to understand what I’m asking :)

Thanks!
