HarmonyOS UIAbility已创建时如何获取分享数据

正常是在UIAbility的onCreate里处理分享数据，比如

onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
  systemShare.getSharedData(want)
  .then((data: systemShare.SharedData) => {
  data.getRecords().forEach((record: systemShare.SharedRecord) => {
  // 处理分享数据
  console.info('share data, title: ' + record.title + ', content: ' + record.content);
});
})
.catch((error: BusinessError) => {
  console.info('share data, error: ' + error.message);
});
}

但如果用于接收分享内容的UIAbility已打开，这时候不会走onCreate，有没有办法获取到want并处理分享数据？
