Currently, PX only supports the authentication with our supported Knowledge Base integrations using a single, shared user account or API token. Therefore, all users will be able to search/view the KB content within Knowledge Center Bot using the permissions and access levels assigned to that user or API token.
It would be a more secure and better user experience if users could only search/view the KB content they are entitled to consume. This option is supported for Zendesk in other comparable applications to PX.
Will investigate the effort on this inQ2
