VMM 2019 cannot add S2D Storage Provider (Windows Server 2019 hyperconverged cluster)

Hi guys, I'm having troubles adding the S2D Storage Provider of a Windows Server 2019 S2D cluster to my VMM 2019 (on Window s Server 2016) server.

The error (number 26311)  is:

error code 1 [SM_RC_NOT_SUPPORTED].

I found this:

https://support.microsoft.com/en-in/help/4036543/error-26311-when-you-try-to-add-a-storage-device-to-the-storage-fabric

but it's not my case, the 2019 cluster is brand new and not an upgraded one. I also did run the Update-ClusterFunctionalLevel but did not solve anything.

Any suggestion?

thanks
