Why Citation and Attribution toggle does not appear in my Add Feature panel?

Hi, I have a question about the Citation & Attribution feature.

According to the documentation, it should appear under:

Workspace → Add Feature → Citations and Attributions

But in my self-hosted Dify, this option does not appear at all.

I’m building a custom Workflow app (not the RAG Chatbot template) and I want the same citation output (segment, score, link to knowledge).

Why is the citation feature missing?

Simply, that’s the feature for chatflow app, not for workflow app.

Workaround:
The result from the Knowledge Retrieval node is simply a variable of type Array[object], so you can pass it to a Template node or Code node to retrieve its contents.
In the screenshot below, the variable is just being dumped as is, but with a bit of ingenuity, you can format it in a more readable way before presenting it to the user in the Output node.
