Problem with multiple custom type post loop and pagination

Hi!!

I’ve a problem with a loop. It’s made-up with multiple custom type post, and pagination doesn’t work fine.
I want a pagination for all custom type post, not for each one.

Code:

$paged2 = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1;
$args = array('post_type' => array('activities', 'conference','post'),'paged' => $paged2,'posts_per_page' => 5);

$the_query = new WP_Query($args);

if ($the_query->have_posts()):
    while ($the_query->have_posts()): $the_query->the_post();
        ?>
        <?php
             $press = get_field(ICL_LANGUAGE_CODE . '_press');
             $documents = get_field(ICL_LANGUAGE_CODE . '_documents');
             $program = get_field(ICL_LANGUAGE_CODE . '_programs');
            if($press || $documents || $program){?>
                <h1 class="entry-title single-title" itemprop="name"><?php echo get_the_title(); ?></h1>
            <?php }

        ?>
    <?php
    endwhile;
      echo '<nav>';
    echo  '<div>'.get_next_posts_link('Older', $the_query->max_num_pages).'</div>'; //Older Link using max_num_pages
    echo  '<div>'.get_previous_posts_link('Newer', $the_query->max_num_pages).'</div>'; //Newer Link using max_num_pages
    echo "</nav>";

Thx!!!!
