event.detail object does not give me dataPoints values

Hi,

I have embedded a powerBI report with JavaScript and I am able to set a function that gives me the event.detail data printed out to a separate div element.

This is the function that does this:

//This function run when data is selected in my embedded PowerBI report

function initializeDataSelection(report, $dataSelectedContainer) {
   report.on('dataSelected', event => {
         var data = event.detail;
         $dataSelectedContainer.text(JSON.stringify(data, null, ' '));
      });
   }

When I click on some data in my PowerBI report, the following is printed out to my dataSelectedContainer div:

{
  "report": {
    "id": "anonymized",
    "displayName": "anonymized"
  },
  "page": {
    "name": "ReportSection",
    "displayName": "anonymized"
  },
  "visual": {
    "name": null,
    "title": "anonymized",
    "type": "slicer"
  },
  "dataPoints": [
    {
      "identity": [
        {
          "target": {
            "table": "anonymized",
            "column": "anonymized"
          },
          "equals": "TESTVARIABLE"
        }
      ],
      "values": []
    }
  ],
  "regions": null,
  "filters": []
}

The data i need is the dataPoint "values": [] (shown in red above)

Questions:

1. Is this feature not supported yet?

2. Is this the wrong object to use to retrieve the dataPoints[0].values array?
