How do I specify multiple rows in an Azure Vulnerability Assessment baseline definition in my ARM (JSON) template?

Question

I'm trying to add some Azure Vulnerability Assessment baseline definitions to my ARM templates. I use JSON for my ARM templates. I cannot find any documentation on how to specify certain VA baseline definitions, though, namely ones that need to have multiple rows in the baselines.

Specifically, I'm trying to add a baseline defintiion for VA2109. I can locate the documentation for how to define a baseline VA entry in a general sense, which is here...

https://docs.microsoft.com/en-us/azure/templates/microsoft.sql/servers/databases/vulnerabilityassessments/rules/baselines?tabs=json

And then I can locate the description of VA2109 in here ...

https://docs.microsoft.com/en-us/azure/azure-sql/database/sql-database-vulnerability-assessment-rules#authentication-and-authorization

But neither of those tell me how to include more than one user-role mapping. For example, below is what I currently have, which works and lets me specify that a user should have data writer role. But, I also want to specify that the user should have data reader and ddl admin roles.

{
  "type": "Microsoft.Sql/servers/databases/vulnerabilityAssessments/rules/baselines",
  "apiVersion": "2021-02-01-preview",
  "name": "[concat(variables('sqlServerName'), '/', variables('databaseName'), '/default/VA2109/Default')]",
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers/databases', variables('sqlServerName'), variables('databaseName'))]"
  ],
  "properties": {
    "baselineResults": [
      {
        "result": ["wibuser", "db_datawriter"]
      }
    ]
  }
}

I was able to find an example of what I want using PowerShell. In PowerShell, you can just provide and array of arrays. The PowerShell example can be found here ...

https://docs.microsoft.com/en-us/powershell/module/sqlserver/new-sqlvulnerabilityassessmentbaseline?view=sqlserver-ps#example-2--create-a-new-security-check-baseline-manually

So I adjusted my ARM to do the same thing, but it throws an error saying invalid ARM template. The adjusted ARM I tried looks like below ...

{
  "type": "Microsoft.Sql/servers/databases/vulnerabilityAssessments/rules/baselines",
  "apiVersion": "2021-02-01-preview",
  "name": "[concat(variables('sqlServerName'), '/', variables('databaseName'), '/default/VA2109/Default')]",
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers/databases', variables('sqlServerName'), variables('databaseName'))]"
  ],
  "properties": {
    "baselineResults": [
      {
        "result": [
          ["wibuser", "db_datawriter"],
          ["wibuser", "db_datareader"]
        ]
      }
    ]
  }
}

Does anybody know how to specify multiple rows in a VA baseline resource when using ARM JSON? Or perhaps know where to find documentation for all of these VA definitions?
