This screenshot shows the flow diagram for the intent.reg order flow for the PizzaSkill - Visual Flow Designer skill and also shows the property inspector for the flow's invokeCustomEvent state. 12 of the flow's 15 states are visible. The invokeCustomEvent state can be reached by starting with the checkIntent state, transitioning to the resolveBag state, then the orderMore state and then invokeCustomEvent. The invokeCustomEvent property inspector has its Component tab selected. On that tab you can see properties for Action, Action Values, Keep Turn, and Output Parameters. For the Action property, there is a text field which contains the expression ${intentName]}. The Action Values property contains the values OrderDrink and OrderPizza.
