Unraid ZFS trying to add this share to Proxmox

Hi All,
Here is my scenario. I have an NFS pool on an Unraid server. I also have a MiniPC with Proxmox on it where I run all my media servers.

I am trying to mount this ZFS from Unraid into Proxmox. Is there a step by step on how I can do this. I tried to go to Storage in Proxmox and add ZFS but it asks for an ID which I am not sure is the right way?

Thanks
