How do I add a function on a specific post category?

1. you can do that in multiple ways ..
   For example you can do a conditional in the PHP itself with a wp built in function :

   if ( in_category( 'my-category' ) {
    //Do something
   }
   

   or for example, if the script is a javascript you could load the script in a conditional way , so it would not load where it is not needed – it will save also some processing time (change the condition to what you want).

       function dl_add_js_conditional() {
   
           if (!is_admin()) { //if is not admin - will load only on front-end
               wp_register_script('myscript_name_js', get_bloginfo('stylesheet_directory') . '/js/myscript_file.js', array('jquery'));
               wp_enqueue_script('myscript_name_js');
           }
   if (is_home()) { //will load only on home
               wp_register_script('myscript_name_js', get_bloginfo('stylesheet_directory') . '/js/myscript_file.js', array('jquery'));
               wp_enqueue_script('myscript_name_js');
           }
       }
       add_action('init', 'dl_add_js_conditional');
   

   Or , you can also do the detection / condition in the script itself (you did not specify what script you use, Jquery, Javascript or other)
