I have a question about using Jira Confluence. We are currently using Jira and Confluence with a company called A. They invited us to create an account. I want to create a new (Confluence) space and update the materials internally, but I don't want my internal materials to be open to Company A. If I create a space with private settings, even if I am an administrator of Company A, will they have the right to see my internal materials? I'm asking because I don't have a clear confirmation of this. Please confirm.
