Of course, as soon as I post my question, I stumbled up on the answer. Answering my own question here for the benefit of others…..
This is somewhat accomplished by setting the call to the microflow to use a confirmation progress bar. Within the Edit Action for the button that is used to call the microflow, look at the Events section, and when the “On click” is set to “Call a microflow” you’ll see another option titled “Microflow settings”. Click on the Edit button to get the screen I’ve pasted below:
This is where you can specify whether the user gets a confirmation before actually triggering the microflow or not. Yeah!!!
Thanks for asking your question on the forum. In case you need to apply more custom logic on either the accept or cancel action, you could consider using the Show confirmation action in the Nanoflow Commons module as well. This action enabled you to use your own button captions as well. As you can see in the screenshot, you will be able to apply custom logic in the true and false branch.
Hopefully, this helps.
