title: Disable `show code` button in Canvas storybook
body: <p>I use Canvas tag from storybook:</p>
  <pre><code>&lt;Canvas&gt;
    &lt;Story name=&quot;Hello&quot;&gt;
      {MyStory.bind({})}
    &lt;/Story&gt;
  &lt;/Canvas&gt;
  </code></pre>
  <p>If i add this code in my <code>.mdx</code> file there appear the code source, but i want to disable the button that is responsible to show the source code.
  <br>Question: How to achieve what i described?</p>
