HarmonyOS 如何禁用image长按？

@Entry  
@Component  
struct Index {  
  
  build() {  
    Column() {  
      Column() {  
        Text('长按')  
        Image($r('app.media.startIcon'))  
          .width(500)  
          .height(200)  
          .draggable(false)  
          .gesture(  
            LongPressGesture({ repeat: true })  
              .onAction((event?: GestureEvent) => {  
                if (event) {  
                  console.log(`LongPressGesture event`)  
                }  
              })  
          )  
      }  
      .width('100%')  
      .height('100%')  
      .justifyContent(FlexAlign.Center)  
      .alignItems(HorizontalAlign.Center)  
    }  
  }  
}
