It has the content below {{node :json}} added, you just need to get the correct data out of the node object.

    <button mat-icon-button matTreeNodeToggle
            [attr.aria-label]="'toggle ' + node.filename">
      <mat-icon class="mat-icon-rtl-mirror">
        {{nestedTreeControl.isExpanded(node) ? 'expand_more' : 'chevron_right'}}
      </mat-icon>
      {{node | json}}
    </button>
