Which of the following is not a method for restricting dashboard access?

Public links serve as a way to share content openly with individuals who receive the link, making it accessible without any restrictions related to user permissions or attributes. This means that anyone with the link can access the dashboard. In contrast, user attributes, role-based filters, and permissions are designed to control and limit access to dashboard content based on specific criteria, ensuring that only authorized users can view or interact with certain information. This differentiation highlights why public links do not function as a method for restricting access, hence making it the correct choice in this context.
