How to elevate your role to security admin in ServiceNow [Paris]

Per ServiceNow,
The security_admin role is an elevated privilege role provided with High Security Settings that lets users create and change access controls and change High Security Settings. In the base system, only the default System Administrator (admin) user has the security_admin role. Since it requires elevating privileges, the admin user does not have this role at login. After elevating privileges, the admin user has the security_admin role for the duration of the user session.
