Add Custom Post Type to ‘At a Glance’ dashboard widget:

function wpdocs_add_custom_post_counts() {
	$post_types = array( 'wpdocs-project' );

	foreach ( $post_types as $cpt ) {
		$cpt_info = get_post_type_object( $cpt );
		$num_posts = wp_count_posts( $cpt );
		$num = number_format_i18n( $num_posts->publish );
		$text = _n( $cpt_info->labels->singular_name, $cpt_info->labels->name, intval( $num_posts->publish ) );

		echo '<li class="page-count '. esc_attr( $cpt_info->name ) . '-count"><a href="edit.php?post_type=' . esc_attr( $cpt ) . '">' . $num . ' ' . $text . '</a></li>';
	}
}
add_action( 'dashboard_glance_items', 'wpdocs_add_custom_post_counts' );

The Custom Post Type is shown with the same style as default Posts, Pages and Comments use, including number of posts and link to CPT list.
