issue about trace the knowledge base chunks

[tigerhu3180]

I want to trace which files the knowledge base chunks cited by the AI's answers come from because I found some errors in those chunks, but I can't find the way to do it.

As shown in the image below, the chunks references are displayed as images, but the documentation has been simplified by ragflow, making it difficult for me to visually identify which file it originates from.

What citation highlighting strategy is currently used in ragflow v23.0? If I want to use the older yellow highlighting feature, what is the underlying principle? If I want to modify the latest version to use yellow highlighting of the original text, which file in the source code should I modify? What was the last version to use the yellow highlighting feature? @dosu
