The admin user functions as the individual managing user management, creation and roles. This means that when you are not the admin of your account, you cannot create, or add user roles.
This is done to prevent users from receiving undesired permissions and guarantee security for you as a merchant.
Therefore, if you would like to get new roles granted to you, please reach out to your admin. Unfortunately Support cannot assist you with getting new roles and will also redirect you to your admin.
It is important to note that an admin can only grant a role that they possess themselves. In case they do not have that role, they can request it by submitting a ticket to Support. For security reasons, no users or roles can be added over the phone.
