Lumira self service storyboard for business analysts

Hi, I would like to know how a business analyst would work on a storyboard in production to create his/her own version of story or visualization, with a live scenario (steps would be great)

I checked below links and they are very helpful in understanding the concept/basics

Thanks for your help
