Most of my Software Engineers only use Miro when there is a workshop conducted by an agileist, software engineering manager, or architect. Then they look or search with Confluence before they go to Miro. Often, we organize piles of stickies as we go, but not always.
Frame with a list of stickies. Generate stickies. Closing remarks, and you can decide how to save the summary as an intention that you can come back to.
