Would be nice to restrict certain groups/users in Confluence from using the Share function, in other words, if such a user tries share a page with some restricted groups, a message should appear saying something like this "You don't have permission to share to this group"

There will be cases where we want to share some pages with specific users without them being able to share with other unlicensed or external users. We currently have public links, but once a public link is enabled, any user has access to the data.
