Do PreBackupScript and PostBackupScript still work in DPM 2016 (with modern storage)?

I am trying to run a PreBackupScript and a PostBackupScript for a protected Hyper-V virtual machine.

The vm runs on a Windows Server 2016 failover cluster and runs Windows Server 2016 as the guest OS.

I modified ScriptingConfig.xml to match what I have used before, including using instructions by Mike Jacquet in this forum on how to obtain the DataSourceName for Hyper-V virtual machines.

The virtual machine itself is named TFS2018 and using Mike's instructions I issued this SQL Query:

select ComponentName,caption from tbl_RM_RecoverableObject
order by cast (Caption as nvarchar)

A subset of the results:

ComponentName                                                     caption
C:\ClusterStorage\Volume1\Tfs2018\TFS2018.vhdx   C:\ClusterStorage\Volume1\Tfs2018\TFS2018.vhdx
A28F5AAC-9D57-4007-AC0A-9B77EACCBF20            TFS2018

I am using A28F5AAC-9D57-4007-AC0A-9B77EACCBF20 as the DataSourceName.

Is that correct?

The recovery point job runs ok, but it looks like the scripts are ignored.

Protection group looks like this:
