showing combobox as editor type instead of listbox in report viewer

[Krunal]

I'm trying to show comboboxes instead of list using following lines of code but it is not working. It keeps showing me the listbox only.
My version is 18.1.24.514 and given code is part of angular application in my typescript file.

this.viewer = $('#reportViewer')
      .telerik_ReportViewer({
        serviceUrl: `${environment.apiUrl}/reportdesigner/`,
        reportSource: {
          report: `${reportName}`,
          parameters: {
            editors: {
              singleSelect: 'COMBO_BOX',
              multiSelect: 'COMBO_BOX',
            },
          },
        },
        parametersAreaVisible: true,
        parametersAreaPosition: 'TOP',
      })
      .data('telerik_ReportViewer');

Any help on this?

            singleSelect: 'COMBO_BOX',
          },
