On the 'Appointments Page' of the application, you will be asked to select either 'Person', 'Corporate' or 'Other Legal Entity'. If you are adding a natural person (i.e. a human), please select 'Person' and fill out your personal details.

Once this section is complete, it will bring you back to the appointments page, where you can then add the details of the second officer, by selecting either 'Person', 'Corporate' or 'Other Legal Entity' again.
