Payroll courses in Denmark

Hi everyone, I'm transitioning from Business and Management to Payroll and HR. I studied for a BSc in Business and Management, and after working for several years, I realized it was not for me. Then I had some experience in the HR field and read a lot about payroll articles, and I believe this is for me, especially as I have such a strong passion for numbers. I tried looking for jobs as a payroll assistant or hr assissant and event internship roles, but it seems that companies prefer experienced people. I also speak Danish at a B1 level, but I started five months ago, so I still struggle to write in Danish, so I stick with English for now. My question is if you know any good courses for payroll, so I could gain experience and learn more about it, I believe it would be easier to find a small role if I had some theoretical knowledge as well. I tried looking for some courses, but I prefer ones that focus on Danish policies, etc
