You should be able to easily reference the pages from within the knowledge base in the course of the conversation
The fluidity of interaction is important here. Technically you can always go into your shared knowledge base, find the relevant page, manually copy a link and paste it in the conversation.

In the demo below this is achived through providing you with autocomplete experience for concepts from your knowledge base.
