change links for featured pages

I am working with the custmoizr theme for the first time. I have the site @ https://macrodiver.com

I am trying to figure out how to set the links for the three featured images to custom pages. I tried using the php from the custumizr support which is

add_filter('tc_fp_link_url' , 'my_custom_fp_links', 10 ,2);
function my_custom_fp_links( $original_link , $fp_id ) {

    //assigns a custom link by page id
    $custom_link = array(
        //page id => 'Custom link'
        2 => 'https://www.my-custom-url-one.com',
        9 => 'https://www.my-custom-url-two.com'
    );

    foreach ($custom_link as $page_id => $link) {
        if ( get_permalink($page_id) == $original_link )
            return $link;
    }

    //if no custom title is defined for the current page id, return original
    return $original_link;
}

I changed the page ids and links to the ids and pages of my site but still it is not working.

any help is appreciated.

thanks
