This is a single-block plugin for the breadcrumb trail. It’s simple, lightweight, SEO-friendly, and WooCommerce compatibility. It also includes some simple separator icons. It works everywhere: Page Editor, Site Editor, and template files.
<h3>How to customize the breadcrumb</h3>
<ol>
<li>
How to change/remove an item?
<pre><code>add_filter( 'breadcrumb_block_get_item', function ( $item_args, $context, $breadcrumbs_instance ) {
 // Ignore items without context.
 if ( ! $context || ! ( $context['object'] ?? false ) ) {
 return $item_args;
 }

 // Eg: remove a term.
 if ( 'term' === ( $context['type'] ?? '' ) && 'term-slug' === $context['object']->slug ) {
 return false;
 }

 // Eg: Change the title of a page.
 if ( 'page' === ( $context['type'] ?? '' ) && page_id_to_change === $context['object']->ID ) {
 $item_args[0] = 'Make it shorter';
 }

 return $item_args;
}, 10, 3 );
</code></pre>
$item_args is a 3-item array: <code>[$item_label, $item_link, $item_attrs]</code> 
$context is an associative array: <code>['type' => 'item type', 'object' => 'item object']</code>. <code>type</code> can be one of the following values: <code>front_page</code>, <code>home</code>, <code>shop</code>, <code>page</code>, <code>post</code>, <code>single</code>, <code>term</code>, <code>taxonomy</code>, <code>post_type_archive</code>, <code>search</code>, <code>404</code>, <code>paged</code>, <code>author</code>, <code>date_year</code>, <code>date_month</code>, <code>date_day</code>, <code>attachment</code>.
</li>
<li>
How to change the markup of the block?
<pre><code>add_filter( 'breadcrumb_block_get_breadcrumb_trail', function ( $markup, $args, $breadcrumbs_instance ) {
 return $markup;
}, 10, 3 );
</code></pre>
</li>
<li>
How to add or remove the items from the breadcrumb trail?
<pre><code>add_filter( 'breadcrumb_block_get_items', function ( $items, $breadcrumbs_instance ) {
 return $items;
}, 10, 2 );
</code></pre>
</li>
<li>
How to use a custom separator for the breadcrumb trail?
<pre><code>add_filter( 'breadcrumb_block_get_args', function ( $args ) {
 // For example, change separator.
 $args['separator'] = '<svg xmlns="http://www.w3.org/2000/svg" fill="currentColor" width="1em" height="1em" viewBox="0 0 16 16"><path fill-rule="evenodd" d="M3.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L9.293 8 3.646 2.354a.5.5 0 0 1 0-.708z"/><path fill-rule="evenodd" d="M7.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L13.293 8 7.646 2.354a.5.5 0 0 1 0-.708z"/></svg>';
 return $args;
} );
</code></pre>
The custom separator should be an inline SVG. To make sure it displays properly, it should have three attributes: width, height, and fill. The values of these attributes should be as follows: <code>fill="currentColor" width="1em" height="1em"</code>. 
Using this hook, you can customize other attributes such as container, before, after, list_tag, item_tag, item_before, item_after, separator.

How to prepend the blog page to all single posts?
<pre><code>add_action( 'breadcrumb_block_single_prepend', function ( $post, $breadcrumbs_instance ) {
 if ( 'post' === $post->post_type ) {
 $blog_id = get_option( 'page_for_posts');
 if ( $blog_id ) {
 $breadcrumbs_instance->add_item( get_the_title( $blog_id ), get_permalink( $blog_id ) );
 }
 }
}, 10, 2 );
</code></pre>
</li>
</ol>
