When a Service Desk again shares a "How to' item with a customer what type of record is being shared?

How-to content in ServiceNow is authored and stored as knowledge articles in the knowledge base, and when a Service Desk agent shares one with a customer, the underlying record being shared is a knowledge article from the kb_knowledge table.

Content objects are used in the Service Catalog to represent informational links or redirects, not agent-shared how-to guidance from the knowledge base.

There is no distinct record type called a 'How to document' in ServiceNow; how-to guidance is a category of knowledge article.

Information item is not a recognized standard ServiceNow record type used for knowledge sharing between agents and customers.
