[Support request] How to add a logout link after a menu

Hello, I am using Toolset + generatepress currently, based toolset, the logout link is wrapped as a shortcode like [wpv-logout-link]Logout[/wpv-logout-link], it seems that can not be added to wordpress menu, I think that it may need to add function.php, I am not a developer, so could you please tell me how I can add the Logout link onto menu? if the users is guest, show log in and if users are logged in, show Logout like your site? Thank you so much!
