I need to make a Knowledge base for our company customers. But I cant get how to make it. I thought I can make a KB only in Confluence as a space but then I saw that I can create a KB in Jira via Service Desk? I am puzzled. Can you plese tell me what is difference? What is better to choose if I want customers to be able to see only articles, FAQs and not other projects and our company tasks and documentation. Thank you.
