The practical signal
A shared mailbox or a shared password makes it difficult later to see who has access. In an incident, it can also be unclear who is allowed to carry out an export.
Cloud access is easy to distribute and therefore must be managed as carefully as access to a physical recorder.

Inventory accounts, rights, linked devices and external parties. Determine who is the owner of the subscription and who may make changes or restore it.
Use personal access, minimal rights, and a fixed procedure for departure or loss of a device. Keep export and management separate if the service supports it.
Remove a test user and verify that live view, backup, and export access are revoked. Record owner and recovery information in a secure location.
You can then not withdraw or audit access per person.
Only if that is explicitly agreed and periodically evaluated.
