I created a Space in confluence that is specific for discussions and topics to discuss with members from outside our own company.
Once the space is created, I can't establish the set-up that a certain user can ONLY access one specific collaboration space.
E.g. If we have 20 spaces, one of the 20 spaces will be named companyx_Colaboration. In that particular space, I want to add people from outside our company. However, those people should only be able to see in our Confluence that only page.
Please could you explain me how to establish this?
