I solved it with jQuery

Code that worked for me:

    jQuery(document).ready(function($) {
        $('a#tab-zadaj-pytanie').click(function() {
            $('#tab-title-zadaj-pytanie a').trigger('click');
        });
        $('button#tab-booking-system').click(function(){
            $('#tab-title-booking-system a').trigger('click');
        });
    });
