body: <p>I'm trying to remove the margin horizontal that is applied to the button text but I'm unable to remove it
  and also when I change the category it is not getting applied, can someone provide me with a an example on how to remove the button text margin (using custom mapping)</p>
  <p>Here is the code for the category also</p>
  <pre><code>   &lt;Button
        status=&quot;primary&quot;
        size=&quot;tiny&quot;
        appearance=&quot;ghost&quot;&gt;
        {(props) =&gt; (
          &lt;Text {...props} category=&quot;p1&quot;&gt;
            Edit
          &lt;/Text&gt;
        )}
      &lt;/Button&gt;
  </code></pre>
