Ask How can I create private group within a membership site?

[SuperAffiliateX]

I want to create a private group inside my membership site but I don't know where to start. I need a space where only certain members can interact, share content, and have discussions. Should I use a plugin or a built-in feature? I also want to make sure it's easy to manage and secure. What's the best way to set this up without making it too complicated?
