Need advise about knowledge base

[Marta Solohub]

Hi Support,

I have added confluence knowledge base to servicedesk, but when I am trying to search some articles from that space it is not working.
I saw a video when you search for smth you receive  a list of how to articles as well and when clicking on one of them a pop-up with instructions (article from Confluence) appears.

Can you please let me know what I have missed?
