How to conditionally show content if user is logged in

I’m going really well with Wappler but am struggling with documentation being older than Wappler and some bits not being there at all.

I have a nav menu which is in an include file. I want to only show the ‘Log out’ menu item if the visitor is logged in. I’ve added the Conditional Region component but I just can’t see what needs to go in the ‘Condition’ field.

Can you give me a steer in the right direction?
