HACS resource issue (under Proxmox)

I create a lovelace minimalist dashboard, but when I install the prerequisited HACS resources, it says:

“since you are not using Lovelace in storage mode you need to manually add the resource with these settings”

HA is under Proxmox

  • What is storage mode?
  • Should I put lovelace into storage mode?
  • how can I do it?

Currently, none of the resources work

EDIT:
Tried putting Lovelace to storage mode, but looks like it doesn’t work
