WordPress query string to change SEO friendly URL

I want to create SCO friendly URL in the WordPress. Also, I have added a hook in my functions.php file as below code but not working.

My URL:http://bddlabs.com/webinar01/?id=pzlyglhbepotwpvbigdatadim_data&storyid=Story_997e9391-71d7-4fac-804b-de891c7aa595

I want http://bddlabs.com/webinar01/pzlyglhbepotwpvbigdatadim_data/Story_997e9391-71d7-4fac-804b-de891c7aa595

Is it possible? I am not sure about it. URL query string is coming from the third party, URL query string is coming from the third party, page content render based on query string.

Below code added landing-page-15.php it WordPress theme base page template

function fb_change_search_url_rewrite() {
    if ( ! empty( $_GET['storyid'] ) ) {
        wp_redirect( home_url( "/webinar01/" ) . urlencode( get_query_var( 'storyid' ) ) );
        load_template( realpath(__DIR__ . '/..') . '/landing-page-15.php' );        
        exit();
    }   
}
add_action( 'template_redirect', 'fb_change_search_url_rewrite' );
//additional rewrite rule + pagination tested
function rewrite_search_slug() {
    set_query_var('storyid', $_GET['storyid']);
    add_rewrite_rule(
        'find(/([^/]+))?(/([^/]+))?(/([^/]+))?/?',
        'index.php?id=$matches[2]&storyid=$matches[6]',
         'top'      
    );
}
add_action( 'init', 'rewrite_search_slug' );
