Which action is NOT permitted by the Editor role?

The Editor role in Appian is primarily focused on content creation and modification within applications. While users with this role can upload, download, and view documents, they typically do not have the ability to modify Security settings.

The ability to modify Security settings is a more privileged action typically reserved for roles that require higher-level administrative permissions. This ensures that sensitive configurations regarding data visibility and access control are managed by those with the appropriate authority and understanding of the implications.

Therefore, modifying Security settings is not within the responsibility or permissions of the Editor role, which is why that option is the correct answer.
