Restricting non-logged-in users from voting using shortcode

When using the shortcode implementation of the plugin [likebtn], it doesn’t respect the settings in the admin.

For example, in the admin, I have “Show a modal window with the message asking to login when guest votes” selected under “who can vote”, but using the shortcode, anyone visiting the site is able to vote. The non-shortcode buttons work fine.

I want to be able to restrict everyone from voting unless they are logged in, but the shortcode doesn’t seems to use the other settings in the admin, and there is no documentation on if/how you can add that setting to the shortcode.

Thank you
