ANZSCO 262112 - ICT Security Specialist employment duties for work experience letters from my employers

Anyone applied for ICT Security Specialist? The ANZSCO 262112 tasks are mostly irrelevant to the responsibilities of a typical Cyber Security Engineer. Could you guide me on how I should prepare work experience letters from my employers to match the tasks mentioned by the Australian Computing Society (ACS) - https://www.acs.org.au/cpd…/cybersecurity-courses.html?
