It works. I am grateful for your support.

Hello,
Thank you for your advice. But it did not work.
Maybe… when insert add block to a “Page”, latest post list use ul and li tags.

Your advice …

<header class="entry-header">
   <h1 class="entry-title"><?php the_title(); ?></h1>
  </header> <?php endif; ?>

 <center><?php the_post_thumbnail('post-thumbnail'); ?></center>

 <div class="entry-content">

On the other hand,
Source added latest posts list …

<ul>
  <li>
    <div class="wp-block-latest-posts__featured-image">
      <img src="featured-image"> </div>
        <a href="****">title</a>
           <time>***</time>
             <div class="wp-block-latest-posts__post-excerpt"> post content </div>
  </li>
</ul>

Therefore… I would like to move div-tag including img-tag after time-tag.
