Could you let me know how to add processor in Payroll Control Center?

Hi Payroll Expert.

Thesedays, I have been configuring PCC demo.

But I don't know how to add processor ( i.e. Payroll Manager ) in PCC.

Could you guide me how to add ( assign ) some user ( EC or On-Premise ) to Processor or Payroll Manager? ( with Role or other things )

Could you let me know how to add processors in PCC.

Best Regards

JB
