Question How to limit topic content from public?

I wanted to hide or unable public to view topic content in my forum. I've been looking and doing some trial and error with the backend. Tried following kunena setup for categories and access. It ended up hiding everything of the categories from public. Help pls.

Not a single topic but all the topic inside categories. Your solution will only limit access of the categories to the public. What I mean is the post and topic inside categories. For example, topic How To Limit Topic Content From Public? I want to hide this content to the public.

backend - kunena - configuration - security - Registered Users Only = Yes

Will only hide everything from Public. The worse happened when I chose this option, if I try to view at public the first search would be ok everything such as main forum and categories will be visible to public. However,after a click on anything and then when I refresh the forum as public everything is hidden. I wanted to attract members, hiding everything can backfire.
