In the registration request form for the Canal d'Alertes service - module e-TRAM, it is necessary to designate a "person responsible for the service", who will be the "main contact person with the AOC consortium for everything related to this service ".
This person is the one who will receive the email of registration of the test environment and the real environment of the service. This person designated at the top is the first person to administer the actual environment. With this role you will not see the cases.
Once registered, you can make any changes you see fit, and you can freely make all the people you consider an administrator, recipient or whatever is appropriate. Each profile or role assigned to a person will require a combination of user + password. Therefore, a person can have one or more users and roles at the same email address.
