Posts from custom port type not showing

I created custom post type in my functions.php with the following code:

`function awesome_custom_post_type(){
$labels = array(
‘name’ => ‘Portfolio’,
‘singular_name’ => ‘Portfolio’,
‘add_new’ => ‘Add Item’,
‘all_items’ => ‘All Items’,
‘add_new_item’ => ‘Add Item’,
‘edit_item’ => ‘Edit Item’,
‘new_item’ => ‘New Item’,
‘view_item’ => ‘View Item’,
‘seach_item’ => ‘Search Portfolio’,
‘not_found’ => ‘No items found’,
‘not_found_in_trash’ => ‘No items found in trash’,
‘parent_item_colon’ => ‘Parent Item’
);
$args = array(
‘labels’ => $labels,
‘public’ => true,
‘has_archive’ => true,
‘publicity_queryable’ => true,
‘query_var’ => true,
‘rewrite’ => true,
‘capability_type’ => ‘post’,
‘hierarchical’ => false,
‘supports’ => array(
‘title’,
‘editor’,
‘excerpt’,
‘thumbnail’,
‘revisions’,

),
‘taxonomies’ => array(‘category’, ‘post_tag’),
‘menu_position’ => 5,
‘exclude_from_search’ => false
);
register_post_type(‘portfolio’,$args);
}
add_action(‘init’,’awesome_custom_post_type’);`

The Portfolio is added on my dashboard and I can create a post.
the Problem I see is that,when am in post and click on the permalink it gives me a 404 error so I can view the post.

How can I view the Post?

I tried adding another file called single-portfolio but still it didn’t work:

`get_header(); ?>
<div id=”primary” class=”content-area”>
<main id=”main” class=”site-main” role=”main”>
<?php
while ( have_posts() ) : the_post();
get_template_part( ‘template-parts/content’, get_post_format() );
the_post_navigation();
// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) :
comments_template();
endif;
endwhile; // End of the loop.
?>
</main><!– #main –>
</div><!– #primary –>
<?php
get_sidebar();
get_footer();`
