It depends on the order of the ability set in the object editor.
If you set the order string of the ability to be "chainlightning" for example, you would order a unit using the action "Unit - Order ___ to chainlightning whatever". There are 3-5 actions for this I believe. It will depend on whether the order is a point order, a target order, an immediate order or whatever else it can be.
