HarmonyOS 鸿蒙Next 如何在普通类中调用自定义组件，并正常展示

import { ComponentContent, UIContext, window } from '@kit.ArkUI'
import { hilog } from '@kit.PerformanceAnalysisKit'


class FakeToastManager {
  private currentContent: ComponentContent<Object> | undefined = undefined

  action(uiContext: UIContext) {
    this.currentContent = new ComponentContent<string>(uiContext, wrapBuilder(BuilderFake), '我是传递的内容')
    uiContext.getPromptAction().openCustomDialog(this.currentContent, {
      autoCancel: false,
      alignment: DialogAlignment.Bottom,
      isModal: false,
      offset: {
        dx: 0,
        dy: '-90vp'
      }
    })
    setTimeout(() => {
      uiContext.getPromptAction().closeCustomDialog(this.currentContent)
    }, 2000)
  }

  // Preview不可用，需要运行在模拟器跟真机
  actionFake() {
    window.getLastWindow(getContext()).then((windowClass) => {
      let uiContext = windowClass.getUIContext()
      this.action(uiContext)
    })
  }
}

@Entry
@ComponentV2
struct Index {
  private fakeToast: FakeToastManager = new FakeToastManager()

  build() {
    Navigation() {

      Column() {
        Button('Fake Toast').onClick(() => {
          this.fakeToast.action(this.getUIContext())
        })
        Blank()
        Text('在fake toast展示时不影响界面点击').onClick(() => {
          hilog.debug(0x000000, 'rainrain', 'click ---')
        })
      }.size({ width: '100%', height: '100%' })

    }.size({ width: '100%', height: '100%' })

  }
}

@Builder
function BuilderFake(text: string) {
  FakeToast({ text: text })
}

@ComponentV2
struct FakeToast {
  @Param text: string = ''

  build() {
    Column() {
      Text('我是假Toast')
      Text(this.text)
    }.backgroundColor(Color.Green)
  }
}
