Change IP Address reservation to Static type using powershell

We are very happy with the new automation possibilities of IPAM 4.5 but are having difficulty to create new reservations with "Static" type.
The example commands documented here IPAM API · solarwinds/OrionSDK Wiki · GitHub

Invoke-SwisVerb $swis IPAM.SubnetManagement FinishIpReservation @("", "Reserved")

Create a reservation for an IP address fine. But how to create or set an reservation to "Static" instead of "Dynamic" Type?

Can we also add a comment using the API?

Does someone have a working example?
