How to put Source URL on RAG Skill answer

[ShumaS]

■Objectives
I want to create a RAG Skill using the ServiceNow Now Assist Skill Kit that meets the following requirements:

1. Trigger: Clicking a button on the incident resolution screen
2. Functional Overview: Interpret the `short_description` and `description` fields of the current incident and suggest a resolution
3. Search Sources: Knowledge and past incident history
4. Functionality: Includes links to the source information used to determine the resolution

In short, I want to create a feature for agents that functions similarly to NAVA’s AI Search feature, but with incidents added as a search source.

■ Questions
Is this requirement feasible?
How can it be implemented?
I believe it might be possible by reverse-engineering the execution flow of NAVA’s AI Search feature—search → answer generation + link addition + response—but could you explain each step of this flow?

■ Progress
I attempted to build this myself but ran into difficulties with step 4.

My implementation method is as follows:

1. Call the RAG Tool using NowAssistSkillKit
2. Generate URLs for the Knowledge and Incident references from the RAG results
3. Create a response from the RAG results + attach the data generated in step 2

However, step 2 did not work as intended.

When I inquired with NowSupport about the NAVA implementation, I received the following response.
However, due to my own limitations, I was unable to fully follow and understand the entire NAVA response process.

>Where is the instruction to include links in the answer card specified?
The instruction to include links in the Now Assist answer card (Q&A Genius Result) is specified within the EVAM (Entity View Action Mapping) View Configs.
Specifically, configuring the SN_Temp_Multi Content Citation QnA or SN_Temp_Multi Content Citation CATALOG mappings allows Now Assist to display clickable links in the Virtual Agent or Service Portal search results.
