How to get the historical changes of constituents of a RIC chain, via DSS (or API)?

in DSS

For example, for 0#.DJI, I would like to know the historical changes of the constituents, i.e., when a constituent was added and removed precisely?

    You can use the Search/HistoricalChainResolution endpoint to resolve current and past chain constituents given a Chain RIC. Instruments may be currently active, or inactive 'historical only' instruments.

    For example, the request is:

    {
      "Request": {
        "ChainRics": [
          "0#GC:"
        ],
        "Range": {
          "Start": "2022-03-27T00:00:00.000Z",
          "End": "2022-03-28T00:00:00.000Z"
        }
      }
    }

    The output contains:

    {
        "@odata.context": "https://selectapi.datascope.refinitiv.com/RestApi/v1/$metadata#Collection(DataScope.Select.Api.Search.HistoricalChainInstrument)",
        "value": [
            {

                        "Description": "Historical Instrument",
                        "InstrumentType": "Unknown",
