How to define array variable in eclipse designer plugin?

Hello, I am trying to have a multi-instance task node to have a few fixed assignees in the diagram. In order to do that, it seems I need to have an array of strings as a variable.

I have no problem passing in such variable but I am not sure how to directly define it in the designer. Is it “data object” I should be looking at? Even though, I am not sure how to define an array of strings in the data object tab…

Hi kernelogic.

Process model example:

You can define data objects for the process model in the flowable-modeler app.
