Knowing how to use Miro would be a technical skill, but having the user experience and design skills to take a concept and design an elegant board to meet business objectives would be a professional skill.

Such a thought-provoking question! 
 

I agree with @Kiron Bondale in that, say, knowing how to use Excel, is a “software proficiency” or “fluency” but knowing how to ‘build financial models’ or statistical models ‘for XYZ use case/business objective’ using excel is a more of a professional skill.
 

With Miro, Kiron has outlined a few examples; off the the top of my head I can brainstorm a couple more examples: 

• Dynamically facilitate day-long workshops of 25+ participants 
• Lead agile rituals or design sprints. 
• Design and analyze business systems and processes
