How to configure XMPP to allow all logged in user to see each other and chat with each other?

I am new to XMPP. I am using Openfire server, and created a console client using Smack library.

My usecase:

All users anonymous, logged in (In future, website visitors) will be able to see other anonymous, logged-in users. And they can initiate a private chat (one-to-one) with any of them.

So, I am able to logged in as Anonymous user, but I am not able to see other Anon / Logged in users (using Roster), because they are not in anon user's roster.

So, What should be configuration OR custom=component/code to to achieve this usecase?

Do I need to create server component? Any hint? OR

It can be done using proper configuration?

Cheers
