Navigation links in custom template

Hi there,
i found Sage and i immediately loved it but i have a (stupid?) question.

I made a template for display post of one category into a static page.

this is page-press.php

   <?php 
    /** 
     * Template Name Press Template 
     */ 
    ?> 
    <?php get_template_part('templates/page', 'header'); ?>
     <?php while (have_posts()) : the_post(); ?>
         <?php get_template_part('templates/content', 'iog_press') ?>
     <?php endwhile; ?>
    <?php the_posts_navigation(); ?>

and this is content-iog_press.php

  <div id="nav-toolbar" class="btn-toolbar" role="toolbar" aria-label="letter-selector">
    <div class="btn-group" role="group" aria-label="letter-selector">
    <?php
        //global $wpdb;
        $years = $wpdb->get_results( "SELECT YEAR(p.post_date) AS year FROM wp_posts p 
        LEFT JOIN wp_term_relationships rel ON rel.object_id = p.ID
        LEFT JOIN wp_term_taxonomy tax ON tax.term_taxonomy_id = rel.term_taxonomy_id
        LEFT JOIN wp_terms t ON t.term_id = tax.term_id
        WHERE p.post_type = 'post' AND p.post_status = 'publish' AND t.term_id=49 GROUP BY year DESC" );
        foreach($years as $year) { ?>
            <button type="button" class="btn btn-default <?php if ($year->year==date('Y'))  echo ' active'?>" data-filter="<?php echo $year->year; ?>"><?php echo $year->year; ?></button>
            
    <?php } ?>        
    </div>
</div>
<br>
<div id="content">
<?php
    
     $args_press = array (
        'cat'          => 49,
        'post_status'          => 'publish'
        );
    
    $the_query_press = new WP_Query( $args_press);
    if ( $the_query_press->have_posts() ) {
        echo '<ul class="portfolio">';
         while ( $the_query_press->have_posts() ) {
            $the_query_press->the_post();
            echo '<li class="col-lg-12">';
             echo '<article class="col-lg-12 portfolio-desc thumbnail">';
        echo '<div class="greyfot">';
        echo '<div class="col-lg-5">';
        if (has_post_thumbnail($post->ID)) {
                 $retina  = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'thumbnail' );
                echo '<a title="' . get_the_title() . '" href="' . get_permalink() . '"><img src="' . $retina[0] . '" alt="' . get_the_title() . '" style="display: block; width:100%; margin-bottom:5px; box-shadow:4px 5px 7px 0px rgba(0,0,0,0.29)"></a>' ;
            } else {
                echo '<a title="' . get_the_title() . '" href="' . get_permalink() . '"><img width="100%" src="/wp-content/themes/iog-theme/dist/images/logo.png" style="display: block;width:150px"></a>';
            };
        echo '</div>';
        echo '<div class="col-lg-7">';
        echo '<div class="text-center">';
        echo '<a title="' . get_the_title() . '" href="' . get_permalink() . '"><h4>' . get_the_title() . '</h4></a>';
        echo '<div class="press-excerpt">' . get_the_excerpt() . '</div>';
        echo '</div>'; 
        echo '</div>';
        echo '</div>';
        echo '<footer>';
        echo '<div class="press-meta">';
        echo '<span class="published"><i class="fa fa-calendar-o"></i>'. get_the_date() .'</span>';
        echo '<span class="comments-number"><a href="'. get_permalink().'">'. get_comments_number().'</a><i class="fa fa-comments-o"></i></span>';
        echo '</div>';
        echo '</footer>';
        echo '</article>'; 
            echo '</li>';
            }
                echo '</ul>';
                ?>

<?php
    } 
?>    
</div>

My problem is that doesn’t appears navigation link “Newer Post” and “Older Post” :frowning:
