Knowledge article is not getting attached to HR case (Platform, custom table)

[Community Alums]

Hi all,

Do you know what could be the reason for not getting attached a Knowledge article to an HR case (custom table) in the platform? I checked the Table Configuration in the Contextual Search, and it looks fine.

Thank you in advance for your help!

Best regards,
Victoria

What is the mechanism for creating the connection in the first place? Is it a custom UI Action?
