Test against an expression and if it evaluates to a truthy value, execute the Then flow container. You can also add Else If
elements into the Else If flow for additional cases. Lastly, you can add elements to the Else flow as a fallback.
Whenever you have a condition that dictates the flow of a part of your skill, you can use this element to junction these possible outcomes.
${result.number == correctNumber}
Else If
elements that also have a Test property and a Then flow. These can be used to test for other cases so that you don't have to chain If
elements.
