Non-limiting examples of the present disclosure pertain to management over the type of notification that is generated and presented to a user relative to an occurrence of a message notification. Processing is executed that evaluates a relevance of a content update to content that is already presented to a user through host application/service endpoints. This helps determine how to present a graphical user interface (GUI) notification as well as link that GUI notification to existing communications that are identified as contextually relevant. Trained artificial intelligence modeling is applied that executes relevance analysis to aid generation of a GUI notification. Said relevance analysis correlates a content portion, of a content update, with a content sub-range assigned in a live representation of the distributed collaborative canvas, where a live representation is an editable and synchronized representation of the distributed collaborative canvas that presents the content sub-range inline within a host application/service endpoint.
