How to lauch whatsapp contact list

I find a lot of questions on StackOverflow showing how to open whatsapp in a given contact, but what I need is to launch it main screen (contact list).

I am on a fragment and I have tried the following:

1 Intent with category LAUNCHER

fun openWhats() {
    val intent = Intent(Intent.LAUNCHER )
    intent.setPackage("com.whatsapp")
    activityResultLauncher.launch(intent)
}

2 Intent with category MAIN

fun openWhats() {
    val intent = Intent(Intent.MAIN)
    intent.setPackage("com.whatsapp")
    activityResultLauncher.launch(intent)
}

ERROR: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.MAIN pkg=com.whatsapp }

3 Using Intent with api.whatsapp and category ACTION_VIEW

fun Fragment.openWhats() {
    Intent(Intent.ACTION_VIEW).apply {
        data = Uri.parse("https://api.whatsapp.com")
    }.also {
        startActivity(it)
    }
}

ERROR: Cannot open link

4 Using getLaunchIntentForPackage()

fun Fragment.openApp(packageName: String): Boolean {
    val manager = requireActivity().packageManager
    return try {
        val i = manager.getLaunchIntentForPackage(packageName) ?: return false
        i.addCategory(Intent.CATEGORY_LAUNCHER)
        requireActivity().startActivity(i)
        true
    } catch (e: ActivityNotFoundException) {
        false
    }
}

Does not work

Any idea how to achieve this?
