Have Google Map in WP, need to make links

Hello good people. I have a site showing the private airstrips in the UK and have a map of them all. However, I can’t get a “pop up” to show the name of the airfield when you click on a marker, with a link to that airfield card.

Here is my code.

get_header(); ?>
	<div id="primary" class="content-area">
		<main id="main" class="site-main" role="main">
            <!--My New Just Map Stuff-->
 <div class="acf-map">
    <div id="airfiled_map" style="width: 100%; height: 1000px;"></div>
            $justMap = new WP_Query(array(
                'posts_per_page'=> -1,
                'post_type' => 'airfield_card'
     echo the_field('main_map');
     $airfieldMap = array();
     $i = 0;
    $mapLat = get_field('latitude');
    $mapLng = get_field('longitude');
    $airfieldMap[$i]['lat'] = $mapLat; 
    $airfieldMap[$i]['long'] = $mapLng; 
     <!-- <div class="marker" data-lat="<?php echo $mapLat ?>" data-lng="<?php echo $mapLng; ?>"></div> -->
<?php echo the_title(); ?>
echo paginate_links();
    <script type="text/javascript">
        var airfieldMap = <?php echo json_encode($airfieldMap); ?>;
        var airfieldMap_zoom = 6;
        var airfieldMap_TypeId = 'terrain'; //satellite

wp_enqueue_script( 'app_js', get_stylesheet_directory_uri(). '/assets/js/airfiled_map.js', array( 'jquery'), '1.0', true );

	</div><!-- #primary -->
