I'm trying to Set up Object Search to find articles related to a customer question in Einstein Bots.
The search works well but for some reason I can not surface any custom fields of the Knowledge object because they don't appear in the picklist. I created a custom chatbot user with system admin profile (for testing) and knowledge user permission. So far I was only able to add standard fields (Title, Summary,...) in the chatbot configuration.
Is this a limitation or am I missing something?
FYI: I was following this guide for setting it up: Einstein bots cookbook
