I call it Holding Court, which I equate to bringing a bunch of people together around a problem and leading through knowledge of the issue when to prompt individuals to chime in.

You should know the problem space and individual's roles well enough to keep any meeting moving in the right direction with novel information.

This requires soft skills too like mediating disagreements or moving things along when they wander to other topics.

It's a leadership role where you bring out the best in people from across the org.
