Stage模型下开发的应用如何拉起FA模型开发的应用

import Want from '@ohos.app.ability.Want'; 
import { BusinessError } from '@ohos.base'; 
 
let want:Want = { 
  deviceId: "", // deviceId为空表示本设备 
  bundleName: "com.example.myapplication", 
  abilityName: "EntryAbility", 
  moduleName: "Module1", // moduleName非必选 
  parameters: { // 自定义信息 
  }, 
} 
 
// context为意图拉起的FA模型的AbilityContext 
this.context.startAbility(want).then(() => { 
  // ... 
}).catch((err:BusinessError) => { 
  // ... 
})
