如何使Clarity树视图中的树节点文本可点击？

<clr-tree>
  <clr-tree-node *ngFor="let node of treeData">
    <ng-template clrIfExpanded>
      <clr-tree-node-children>
        <clr-tree-node *ngFor="let childNode of node.children">
          <ng-template clrIfExpanded>
            <clr-tree-node-children>
              <clr-tree-node *ngFor="let grandChildNode of childNode.children">
                <clr-tree-node-label [clrTreeNodeClickable]="grandChildNode.clickable" (click)="handleNodeClick(grandChildNode)">
                  {{ grandChildNode.label }}
                </clr-tree-node-label>
              </clr-tree-node>
            </clr-tree-node-children>
          </ng-template>
          <clr-tree-node-label [clrTreeNodeClickable]="childNode.clickable" (click)="handleNodeClick(childNode)">
            {{ childNode.label }}
          </clr-tree-node-label>
        </clr-tree-node>
      </clr-tree-node-children>
    </ng-template>
    <clr-tree-node-label [clrTreeNodeClickable]="node.clickable" (click)="handleNodeClick(node)">
      {{ node.label }}
    </clr-tree-node-label>
  </clr-tree-node>
</clr-tree>
