With the Business Plan, I have two groups. Group 1 is for everyone that is a member. Group 2 is limited. How do I set up access to add a new member so that they are not automatically added as Group 1. How can I add someone so that they can see group 2. Alternatively, how can i give access to someone so that they can only access a certain folder rather than adding them as a member. The setting at the moment mean i cannot share the link. The link is not avaible for some reason
