Add class to links in shortcodes

Hi,

I am having a conflict with another plugin wich allow me to add a pop-up to pages, the problem is that when clicking any of the button of the cookie bar (settings, accept, etc..) it automaticly close the other sites popup

I need to add a class to the button/links of cookieyes gdpr consent, but these buttons are called using a shortcode so i can’t add a class to the links in the admin, is there a way for me to do that in a way it won’t be removed on plugin updates ?

Thanks!
