Currently, we allow all signed-in users to access the Help Center. Mainly so they can see their open support tickets and create new ones.

We're thinking about enabling the Gather/Community feature as well, but I would like to limit it to only a subset/segment of our customers.

In the page hc/admin/general_settings there's a setting called "limit to user segment" that limits the entire help center to a user segment of my choice.

I would like to have the same option for the Community. Is that possible in any way?

The option described by @... above does not restrict access to the Community, only to the topics in the Community. So with that solution, anyone could access the Community but would be limited in what they see. That's not what I want.
