I would like to add statuses to my Epic which are currently not in the list. What rights do I need to have as a user and how can I do this?
Depends on a few things:
If you don't have either of those permissions, I would figure out who your JIRA admin is and see if they can either give you the proper access or make the changes for you.
And if you want to see the statuses on the list you have o use a plugin
