We have enabled Copilot Search in our environment. It uses data from Knowledge Articles to answer for the queries which we ask it.

When multiple distinct searches are performed within the same Copilot session, the interactionContext field on the Copilot Events (msdyn_copilotevent) value is updated to reflect the most recent search, rather than aggregating all Knowledge Article IDs searched during the session. As a result, when reviewing a single Copilot Event record after the session has ended, only the last searched Knowledge Article IDs will be present.

Currently, the interactionContext field does not support storing or appending all searched Knowledge Article IDs across an entire Copilot session.

So I suggest that this interactionContext field should store all searched Knowledge Article IDs across an entire Copilot session
