To add a user:
Select 'Invite user'.
Enter the new user's details and select 'Invite'.
Once invited, they'll receive an email with instructions on how to join your account. Invited users will appear in either "pending", "accepted", "canceled" or "expired"
User types: an 'account manager' has the same access privileges as your main admin account, while a 'subaccount' can control the music only, with no access to account settings.
