Colorado FAMLI account TPA access

Hello, my organization has a Colorado FAMLI account for our one employee in Colorado in order to file and pay the Paid Family Medical Leave tax. We have QuickBooks Desktop Assisted Payroll so I need to add them as a Third Party Administrator. It appears I do that from myfamilyplusemployer.state.co.us > Manage Accounts > selecting account name > click "Add" near the bottom in the section "Third Party Administrator." Is this correct?

If so, then there is a box that says "Select Account." What should I enter here?

Thank you in advance for your help.
