Display only custom post type count for current author on the “At a Glance” dashboard widget

I am using this code to display all custom post types along with their count on the “At a Glance” dashboard widget:

add_action( 'dashboard_glance_items', 'cpad_at_glance_content_table_end' );
function cpad_at_glance_content_table_end() {
$args = array(
    'public' => true,
    '_builtin' => false,
);
$output="object";
$operator="and";

$post_types = get_post_types( $args, $output, $operator );
foreach ( $post_types as $post_type ) {
    $num_posts = wp_count_posts( $post_type->name );
    $num = number_format_i18n( $num_posts->publish );
    $text = _n( $post_type->labels->singular_name, $post_type->labels->name, intval( $num_posts->publish ) );
    if ( current_user_can( 'edit_posts' ) ) {
        $output="<a href="https://wordpress.stackexchange.com/questions/318804/edit.php?post_type=" . $post_type->name . '">' . $num . ' ' . $text . '</a>';
        echo '<li class="post-count ' . $post_type->name . '-count">' . $output . '</li>';
        } else {
        $output="<span>" . $num . ' ' . $text . '</span>';
            echo '<li class="post-count ' . $post_type->name . '-count">' . $output . '</li>';
        }
    }
}

Is there a way to only display the count of posts belonging to the current logged in author?

I think what you’re after is:

   // The user is logged, retrieve the user id (this needs to go above your foreach)
    $user_ID = get_current_user_id(); 
   // Now we have got the user's id, we can pass it to the foreach of your function(this needs to go into your foreach:  
    echo '<li>Number of '.$post_type->name.' posts published by me: ' . count_user_posts( $user_ID , $post_type->name ).'</li>';
