The Adobe Admin Console is only accessible to Admins as it is used to manage the organization.
Are you already an Admin for an organization? If someone has added you as an Admin, you'll have an email with the details.
If you're not an admin, you don't actually need to use the Admin Console.
An administrator is a member of your company. My guess would be that your internal IT help desk knows more about this. But as @Vikrant Rai said, most users don't need to be administrator. So it's depending on your company's policy.
Many thanks to all of you who helped me find a solution regarding this problem, I will be contacting my team which does computer maintenance work.
