HarmonyOS 自定义弹窗有时候能弹出，有时候弹不出

直接在页面点击 "展示自定义弹窗"可以展示，"模拟数据请求失败弹窗"通过model模拟请求数据后也可以展示，但是点击"扫一扫"在打开相机权限之前，需要先展示一个自定义弹窗，此时不显示，请问需要如何处理呢？

请参考该API：https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis-arkui/js-apis-promptAction.md#customdialogoptions11

import promptAction from '@ohos.promptAction'

function customDialogBuilder() {  
  Column() {  
    Text('Custom dialog Message').fontSize(10)  
    Row() {  
      Button("确认").onClick(() => {  
        promptAction.closeCustomDialog(customDialogId)  
      })  
      Blank().width(50)  
      Button("取消").onClick(() => {  
        promptAction.closeCustomDialog(customDialogId)  
      })  
    }  
  }.height(200).padding(5)  
}  
@Entry  
@Component  
struct Index {  
  @State message: string = 'Hello World'  
  build() {
