Hi,
Supporting this will indeed require updating the SDK. However, this is not as simple as just updating the SDK to the new version and be done with it.
The current version of the plugin is based on a version of the SDK from 2019. And there were dozens of new versions of the SDK since then, with many changes each time.
So it will require us to adapt the code of the plugins to the changes. Also, it will require further modifications to add the support of that type of parcels.
To be able to test all of this, we'll need a MyParcel account, which we don't have on our end and can't create as we're not in The Netherlands.
Could you help us with that ?
