Fields for mapping are not shown up in KCS Support Console on admin panel

While trying to set up a KCS Support Console when Admin has already added Salesforce "Article Object API" i.e. "lightning__kav" in SU Admin panel under Search client(SF console) KCS. However, the fields to map are not being shown as per the configuration steps of KCS Support Console.

ENVIRONMENT

CAUSE

Insufficient permissions for Salesforce users to map fields in KCS.
The SearchUnify admin who authenticated Salesforce as a content source is not a Knowledge User in Salesforce.

RESOLUTION

For mapping KCS fields in the SearchUnify admin panel, please ensure that Agents are also a Knowledge User in Salesforce.
Setting up the user as knowledge user in SF org resolves this problem.

How to become a Knowledge User?

1. Log into your Salesforce org.
2. Find Knowledge Settings from Quick Find Box and click Edit.
3. Check Enable Lightning Knowledge (if it's not checked) and click Save.

To map only Knowledge Article fields.
