kendo treelist excel arraylist, fild does not receive array?

[Leonardo]

I have the following situation, a component with treelist where the column receives an array by ngTemplate referencing the field.

 <kendo-treelist-column
    *ngIf="!isHidden('progress')"
    field="progress"
    title="Progress"
    [width]="320">
    <ng-template kendoTreeListCellTemplate let-dataItem let-group="cellContext">
      <app-okrprogress-bar
        [showButtonOk]="true"
        [value]="dataItem.progress.slice(-1)[0].value"
        [valuePercentagel]="dataItem.progress.slice(-1)[0].value"
        [showSlider]="!dataItem.contents ? true : false"
        [showValue]="dataItem.typeProgress == 'Values' ? true : false"
        [showChecbox]="dataItem.typeProgress == 'Boolean' ? true : false"
        [stepSlider]="dataItem.typeProgress"
        [viewValue]="dataItem?.values"
        (newPercentageActive)="
          changePercentage($event, group.viewItem.parent.data, dataItem)
        "></app-okrprogress-bar>
    </ng-template>
  </kendo-treelist-column>

Now I have to export this column in excel, but the field only waits for a simple variable or objects.

  <kendo-treelist-excel>
    <kendo-excelexport-column fild="keyName" title="Objective"></kendo-excelexport-column>
    <kendo-excelexport-column fild="progress.slice(-1)[0].value" title="Progress"></kendo-excelexport-column>
    <kendo-excelexport-column fild="status.status" title="Status"></kendo-excelexport-column>
  </kendo-treelist-excel>

I did some tests of different calling modes but none of the results were effective.

This is the interface:

interface ObjectiveResult {
  keyName: string;
  progress: Progress[];
  status?: Status;
}

interface Progress {
  value: number;
  date: Date;
}

interface Status {
  name: string;
  color: string;
}

Current results:
