Installing Frappe + ERPNext V15 via docker?

I’d like to spin up a docker instance with ERPNext V15 in it. I’m able to follow the guide to get V16 installed in Docker, but I am not sure what I need to do to install V15 instead.

This is one of the way you can spin up the setup

uvx --from frappe-manager fm create mybenchv15 --apps frappe:version-15 --apps erpnext:version-15 --apps hrms:version-15
