Java 有意将TikTok应用程序打开至其主页

我可以用下面的代码打开TikTok到用户的个人资料，但是如何打开TikTok到其主页

Uri uri = Uri.parse("https://vm.tiktok.com/"+"tiktokExtension");
Intent tiktokIntent = new Intent(Intent.ACTION_VIEW, uri);
tiktokIntent.setPackage("com.zhiliaoapp.musically");
startActivity(tiktokIntent);

---

通过以下方式启动tiktok应用程序：

 try{
 Intent intent = new Intent("com.zhiliaoapp.musically");
 startActivity(intent);
 }catch(ActivityNotFoundException e){
 //if the app doesn't exist do some stuff , like redirection to playstore.....
 }
