        VaultAuthType = 'RenewToken'
    }

    Register-SecretVault -AllowClobber -ModuleName SecretManagement.Hashicorp.Vault.KV -Name $Name -VaultParameters $VaultParameters

  # test vault

Also, just setting the VaultToken doesn't work, as in Invoke-VaultToken, it get's deleted if TokenExpireTime is before now (which it is, as it defaults to year 1600).
