How to OpenCore boot of CCC Clone on external USB

Hi! I want to make a CCC clone of my Big Sur Hackintosh on an external USB SSD disk and boot from it. I made the clone, then copied the EFI manually. I'm able to boot from it into OpenCore, but can only choose the installation on the internal disk, not the USB. I searched but couldn't find anything helpful. Even though I'm hackintoshing since 4yrs these kind of things are still very mysterious to me.

My setup: Big Sur, Proxmox VM, Inateck USB Card. Installed using this guide: https://www.nicksherlock.com/2020/06/installing-macos-big-sur-on-proxmox/

Thanks!!
