WordPress page shows 404 when adding to URL

I’m adding rewrite rules to my PHP script which is included in a WordPress page with the permalink kb

So I can visit domain.com/kb and the page is displayed.

function wdm_add_rewrite_rules() {
    add_rewrite_rule( '^kb/([^/]+)/?$', 'kb?kb_cat=$matches[1]&kb_seq=1', 'top');
}
add_action('init', 'wdm_add_rewrite_rules');

But when I visit the page with additional strings in the url, I get a 404.

So when I visit domain.com/kb is shows the correct page, and then visiting domain.com/kb/84/92, it shows a 404

I just need to be able to read the additional url params in my PHP script, such as $_GET["kb_cat"]

    try this:

    function wdm_add_rewrite_rules() {
    add_rewrite_rule( '^kb/([^/]+)/?([^/]+)$', 'kb?kb_cat=$matches[1]&kb_seq=1', 'top');
}
add_action('init', 'wdm_add_rewrite_rules');

    function wdm_add_rewrite_rules() {
    add_rewrite_rule( '^kb$', 'index.php?kb_cat=$matches[1]&kb_seq=1', 'top');
}
add_action('init', 'wdm_add_rewrite_rules');

    to take it a step further and use the parameters:

    function add_query_vars_filter( $vars ){
    $vars[] = "kb_cat";
    $vars[] = "kb_seq";
    return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );

    and then load a custom template file:

    function include_custom_template($template){

    if(get_query_var('kb_cat') && get_query_var('kb_seq')){
        $template = get_template_directory() ."/my-custom-template.php";
    } 
   
    return $template;    
}

add_filter('template_include', 'include_custom_template');

    Once adding to your functions.php go to Settings > Permalinks and hit ‘save changes’ to reset the flush rules
