HarmonyOS 自定义弹窗CustomDialog无法定制closeAnimation，目前默认效果是渐隐，设计要求滑动进入

let anmDuration: number = 300; 
@CustomDialog 
struct CustomDialogExample { 
 controller: CustomDialogController = new CustomDialogController({ 
  builder: CustomDialogExample({}), 
  autoCancel: false 
 })

 @State isAutoCancel: boolean = false;

 build() { 
  Column() { 
   Row() { 
    Text("自定义动画的弹窗") 
   } 
   .borderRadius(20) 
   .padding(8) 
   .backgroundColor('#ff6288cb') 
   .height(200)
