Using EasySocial Comment Integration on EasyBlog - Can Guests post comments?

I'm looking at using EasySocial Comments for my EasyBlog comment system. So in EasyBlog I've turned on the EasySocial integration - but I notice it's not allowing guests to comment.

Is that the way it works - or can I somehow set things so Guests can comment? I see 'Access Rules' the EasySocial back-end and there's one for Add Comments - but it only allows me to Enable / Disable it - I can't see anywhere I can configure it?

Sorry if I'm a bit confused. I guess the basic question is.... Can EasySocial Commenting system be used in EasyBlog for GUESTS as well as logged in USERS?

Thanks!
