How do we connect to a remote SQL DB via a command line (e.g., via a script) so that the novice user can use Bartender without having to do it themselves?  We need to call the "Custom Connections Settings" branch, it would seem.  (Actual names obfuscated)

Running SystemDatabaseWizard.exe via command line such as: "C:\Program Files\Seagull\BarTender 2021\SystemDatabaseWizard.exe" /Silent /Log=C:\temp\BartenderDatabaseConnectionR6.log /Type=Connect /Server=ServerName\InstanceName /Authentication=Windows /Database=DB_name 

The execution log shows an attempt to install SQL Express, which never completes.  SQL Express is already installed by the Bartender 2021 R6 deployment, since we can't prevent that.
