Explicitly defined default values for flow action inputs are now displayed from within the flow. Included with Default Value toggle value will display the explicitly defined
default value that’s sent to the action at run time. Use the Included with Specified Value toggle value to specify another value for the input instead.
How: In Flow Builder, add an Action element to your flow. In the New Action window, search and select the invocable method or flow. Keep toggle off to use the default value or on to specific a non-default value instead
