Pagination in Custom Author Page

Hi Ben,
I made an author page myself like this:

<?php get_header(); ?>

<div class="post-author" style="border: none; padding: 13px;">
	<?php if ( get_theme_mod( 'author_avatar_posts' ) != 'yes' ) : ?>
	<div class="avatar-container">
		<?php echo get_avatar( get_the_author_meta( 'ID' ), 80, '', get_the_author() ); ?>
	</div>
	<?php endif; ?>
	<div>
		<div class="author"><?php the_author(); ?></div>
		<?php the_author_meta('description'); ?>

      <div class="yazarbaglantilari">
<?php
if ( get_the_author_meta('instagram', $theID)) {
$output .= '<a href="https://www.instagram.com/' . get_the_author_meta('instagram', $theID) . '/" target="_blank"><i class="fab fa-instagram"></i></a>';
}
if ( get_the_author_meta('twitter', $theID)) {
$output .= '<a href="https://twitter.com/' . get_the_author_meta('twitter', $theID) . '" target="_blank"><i class="fab fa-twitter"></i></a>';
}
if ( get_the_author_meta('facebook', $theID)) {
$output .= '<a href="' . get_the_author_meta('facebook', $theID) . '" target="_blank"><i class="fab fa-facebook"></i></a>';
}
if ( get_the_author_meta('linkedin', $theID)) {
$output .= '<a href="' . get_the_author_meta('linkedin', $theID) . '" title="" target="_blank"><i class="fab fa-linkedin"></i></a>';
}
if ( get_the_author_meta('youtube', $theID)) {
$output .= '<a href="' . get_the_author_meta('youtube', $theID) . '" title="" target="_blank"><i class="fab fa-youtube"></i></a>';
}
if ( get_the_author_meta('forum', $theID)) {
$output .= '<a href="' . get_the_author_meta('forum', $theID) . '" title="" target="_blank"><i class="fas fa-comments"></i></a>';
}
if ( get_the_author_meta('url', $theID)) {
$output .= '<a href="' . get_the_author_meta('url', $theID) . '" title="" target="_blank"><i class="fas fa-globe"></i></a>';
}
echo $output;
?>
		</div>
	</div>
</div>

<?php do_action( 'ct_mission_news_archive_post_before' ); ?>
<div id="loop-container" class="loop-container">
    <?php
    if ( have_posts() ) :
        while ( have_posts() ) :
            the_post();
            ct_mission_news_get_content_template();
        endwhile;
    endif;
    ?>
</div>
<?php do_action( 'ct_mission_news_archive_post_after' ); ?>

<?php get_footer(); ?>

But pagination is not working. Only the first page is shown. I couldn’t find what code to do this with or what I found didn’t work. What do you recommend?

Thanks.
