How to open launcher's widget picker?

Question

I want to open the launcher's widget picker (for example, the one we get when we long press on home screen) from my Activity. What I want to achieve is, I want to take the user to my widget so that there are more chances that he will consider adding it.

Programmatically adding the widget to home screen will be the best case. But, because that is not possible, I want to go as closer as possible to make user add the widget.

I tried the following but that only opens a dialog (not the launcher's) with all the widgets and by selecting one nothing happens.

Intent pickIntent = new Intent(AppWidgetManager.ACTION_APPWIDGET_PICK);
pickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, 0);
startActivityForResult(pickIntent, 1234);

How to make this work? Any suggestions on this scenario are much appreciated.

It's possible to pin widget to homescreen (official doc) on API 26+:

AppWidgetManager mAppWidgetManager =
context.getSystemService(AppWidgetManager.class);

AppWidgetProviderInfo myWidgetProviderInfo = new AppWidgetProviderInfo();
ComponentName myProvider = myWidgetProviderInfo.provider;

if (mAppWidgetManager.isRequestPinAppWidgetSupported()) {
   Intent pinnedWidgetCallbackIntent = new Intent( ... );
   PendingIntent successCallback = PendingIntent.createBroadcast(context, 0,pinnedWidgetCallbackIntent);

   mAppWidgetManager.requestPinAppWidget(myProvider, null,
       successCallback.getIntentSender());
}
