HarmonyOS promptAction.showActionMenu 接口支持布局为底部布局吗？

参考demo：

import promptAction from '@ohos.promptAction';
import { BusinessError } from '@ohos.base';

function showActionMenu() {
  try {
    promptAction.showActionMenu({
      title: 'Title Info',
      buttons: [
        {
          text: 'item1',
          color: '#666666'
        },
        {
          text: 'item2',
          color: '#000000'
        },
      ]
    }, (err, data) => {
      if (err) {
        console.info('showActionMenu err: ' + err);
        return;
      }
      console.info('showActionMenu success callback, click button: ' + data.index);
    })
  } catch (error) {
    let message = (error as BusinessError).message
    let code = (error as BusinessError).code
    console.error(`showActionMenu args error code is ${code}, message is ${message}`);
  }
  ;
}

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    RelativeContainer() {
      Text(this.message)
        .id('HelloWorld')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
        .onClick(()=>{
          showActionMenu()
        })
    }
    .height('100%')
    .width('100%')
  }
}
