Add additional member or delegate role to employee

I am trying to add a team member to my account or delegate my roles to an employee.  How do I do this?

It is not clear what the desired function is, but in IRIS there is no concept of delegate or team member.

An organisation can have any number of affiliated users, who can create and manage submissions on behalf of the organisation. To be able to see a specific submission, an affiliated uer must be added to that submission as a manager or contributor. It is also possible for Industry Users, in the IRIS portal, to reassign the "Portal contact" role of a given submission (the person who receives all emails by default) to any other user who is already added to that particular submission.

For additional information, please check the IRIS guide to registration (chapters 5 and 6) and the IRIS guide for applicants (chapters 2.4, 2.5, 2.6) in the IRIS guidance page.
