Final answer:
To configure Access Control for the Employee Relations Cases table with Admin and HR Admin roles, you should elevate your role to security_admin through the User dropdown in the application's banner.
Step-by-step explanation:
If you have both Admin and HR Admin roles and you want to configure Access Control for the Employee Relations Cases table, the correct approach would be to elevate your role to security_admin. This can be accomplished by selecting the User dropdown in the banner of the application you are using (e.g., ServiceNow) and choosing to elevate your role. There is no need to add additional roles such as Delegated Developer or to manually add the security_admin role if the elevate role option is available and you already possess the necessary base roles for the task.
