HarmonyOS 鸿蒙Next如何调起发送手机短信的功能但不发送

兄弟，试下这段代码：

import Want from '@ohos.app.ability.Want';
import { BusinessError } from '@ohos.base';
import common from '@ohos.app.ability.common';

@Entry
@Component
struct Index {
  build() {
    Button("跳转到短信").onClick((event: ClickEvent) => {
      let context = getContext(this) as common.UIAbilityContext;
      class info{
        contactName:string
        telephone: string
        // content:String
        constructor() {
          this.contactName = 'ZhangSan'
          this.telephone = '123'
        }

      }
      // class want
      let contactInfo:Array<Object> = new Array()
      contactInfo[0] = new info();
      let want:Want = {
        bundleName: 'com.ohos.mms',
        abilityName: 'com.ohos.mms.MainAbility',
        parameters: {
          contactObjects: JSON.stringify(contactInfo),
          content:"内容",
          pageFlag: 'conversation'
        }
      };
      context.startAbility(want)
        .then(() => {
          //...
        })
        .catch((err:BusinessError) => {
          console.error(`Failed to startAbility. Code: ${err.code}, message: ${err.message}`);
        });
    }).margin(10)
  }
}
