Agent assist doesn't show articles for non admin users

[Akki1]

I've added the agent assist on the Service Operations Workspace for the hr case table and the agent assist show the knowledge articles . But for non admin users it doesn't show any articles and gives me a message "No Matches Found Try modifying your search text or filter to find what you’re looking for in agent assist".

Have you checked 'Search Source' for Articles if there is any role restriction defined?

No such restrictions

Does the non admin users have access to those articles from portal or knowledge view?
