[XCPBETA] Workload is not supported by the current license

[Noritaka971]

Hi,
I'm trying the Veeam XCP backup plugin in a lab infrastructure. Whether I'm using my Rental license or the license provided with the beta ISO, I get the same error message when launching the backup job:
"Failed to perform backup: Workload is not supported by the current license."
Is there a specific workload to provision in the license?
