HarmonyOS 自定义弹窗如何禁止右滑消失、监控右滑行为

参考以下示例：

@Entry
@Component
struct CustomDialogUser {
  dialogController: CustomDialogController = new CustomDialogController({
    builder: CustomDialogExample({
      cancel: () => {
        this.onCancel()
      },
      confirm: () => {
        this.onAccept()
      },
    }),
    onWillDismiss: (dismissDialogAction: DismissDialogAction) => {
      console.info("reason" + JSON.stringify(dismissDialogAction.reason))
      console.log("dialog onWillDismiss")
      if (dismissDialogAction.reason == DismissReason.PRESS_BACK) {
        // dismissDialogAction.dismiss()
      }
      if (dismissDialogAction.reason == DismissReason.TOUCH_OUTSIDE) {
        // dismissDialogAction.dismiss()
      }
    }
  })

  onCancel() {
    console.info('Callback when the first button is clicked')
  }

  onAccept() {
    console.info('Callback when the second button is clicked')
  }

  build() {
    Column() {
      Button('click me')
        .onClick(() => {
          this.dialogController.open()
        })
    }.width('100%').margin({ top: 5 })
  }
}

@CustomDialog
struct CustomDialogExample {
  cancel?: () => void
  confirm?: () => void
  controller: CustomDialogController

  build() {
    Column() {
      Text('我是内容').fontSize(20).margin({ top: 10, bottom: 10 })
      Flex({ justifyContent: FlexAlign.SpaceAround }) {
        Button('cancel')
          .onClick(() => {
            this.controller.close()
            if (this.cancel) {
              this.cancel()
            }
          }).backgroundColor(0xffffff).fontColor(Color.Black)
        Button('confirm')
          .onClick(() => {
            this.controller.close()
            if (this.confirm) {
              this.confirm()
            }
          }).backgroundColor(0xffffff).fontColor(Color.Red)
      }.margin({ bottom: 10 })
    }
  }
}
