I'm building a user guide for our product on Confluence and want to limit permissions for customers that gain access to read through our user guide. I was wondering if the following are possible through confluence:
1. Create a log-in process for clients to auto-populate a "group" that has a certain permission parameter that are granted certain pages to view.
2. Within the left-hand navigation bar, be able to remove the "Blogs", "Questions", "Calendars" or be able to permission them to disappear for a group.

3. On the right-hand side, the ellipses menu, I would like it so that users of a certain group (E.g. the external clients that will have limited access) can ONLY export to PDF and Export to Word. I really don't want them to get any other permission.

Can this be achieved through admin access? Please help!
