How do I access immutable backups that remain in my old Veeam Data Cloud Vault after moving the job?

I moved a Backup Copy job from VDC‑Vault‑1 (immutability 30 days) to VDC‑Vault‑2 (immutability 1 day). The job retention is 7 days, no GFS.

After the move, the old chain showed under Backups → Object Storage → Orphaned for ~7 days, then disappeared (retention). However, ~1.5 TB still shows used in the old vault—both in cloud.veeam.com and in VBR repository usage—which I assume are the immutable objects that can’t be deleted until the 30‑day lock expires (by design for object storage).

My questions:
1. How do I see/access those immutable backups for restore in a disaster?
2. How can I verify cleanup timing as immutability expires (i.e., when those objects actually get removed)?
