Various examples of the present disclosure can be directed to programmatically generating and rendering for display a context pane within a group-based communication interface. In some examples, the context pane comprises context pane content representative of channel membership associated with a communication channel identifier with which the group-based communication interface is associated. Group-based communication objects of a group-based communication data corpus can be utilized (e.g., by way of a trained machine learning model and/or work graph data structures) to inform the determination of context pane content.
