Get-app installation error

I’m installing ERPNEXT 14 on VirtualBox using instructions from GitHub - D-codE-Hub/Frappe-ERPNext-Version-14--in-Ubuntu-22.04-LTS: A complete Guide to Install Frappe/ERPNext version 14 in Ubuntu 22.04 LTS. I encountered an error during

bench get-app payments

saying fatal: repository ‘payments’ does not exist FileNotFoundError: [Errno 2] No such file or directory: ‘home/kim/frappe-bench/apps/payments/setup.py’

How do I resolve this? Thanks!
