Opening Hik-Connect using Intent

I am using below code to open the app named : Hik-Connect as below :

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
            sharingIntent.setClassName("com.hikvision.hikconnect",
                    "CLASS NAME NEEDS TO PASS");
            sharingIntent.putExtra(Intent.EXTRA_TEXT, "GIT Cameras");
            startActivity(sharingIntent);

You can see am using the package name : com.hikvision.hikconnect.

What I have to pass as class name ?

Please guide me. How can I open this application using Intent in Android ?

The app link is as https://play.google.com/store/apps/details?id=com.hikvision.hikconnect&hl=en_IN

Thanks.
