A Service Owner needs to view related items, such as active Incidents and planned Changes,...

The contextual side panel is the correct work area because it displays detailed information about the selected node in Unified Map. When a Service Owner selects the home node or a related CI/service node, the contextual side panel provides supporting operational context such as active Incidents, planned Changes, related records, and other actionable details. This is exactly the requirement in the question: the Service Owner does not merely need to see topology; they need related work items connected to the selected node. The Map itself displays relationships and topology, but it does not provide the detailed related-record panel by itself. The toolbox provides map interaction tools, and content controls influence what layers or types of content are displayed. Neither of those is the correct place to review related Incidents and Changes for a selected node. Therefore, the correct answer is Contextual side panel.
