What it does
Brings the configuration back to a saved version (the current state is saved as a version first). Changes what live visitors see, so it needs the agents:publish scope and confirm: true. Check diff_versions first.
Side effects
Saves the current state as a version, then brings back the chosen one. Visitors of a published agent see it at once.
