Integrate hard drive into Proxmox VE?

Good day,

I subsequently installed a 2TB HDD in my Proxmox server. At first I only had a 128GB SSD for testing, but now I've expanded this to include a 2TB HDD (for data) because I want to host my own cloud.

As you can see in the images below, the HDD is recognized, and I can also create LVMs, etc. If I want to create a VM, I can select the hard drive. If I want to create a Linux container, I can only select "Local," which is the SSD. There would still be 58GB of free space on it, which obviously isn't worth using for a cloud storage. How can I mount the new hard drive so that I can install the cloud service in the container?

I hope someone can help me, thank you
