To style button with a standard SAPUI5 icon
<p>How to style button with a standard SAPUI5 icon? </p>

<pre><code>    &lt;Button
        icon="sap-icon://notes"
         text="Справки"
        press="onOpenRef"
        class=" sapThemeHighlight-asBackgroundColor "/&gt;
</code></pre>

<p>It is necessary that the button was in the shape of a circle and green.</p>

<p>How can I do it (preferably standard SAPUI5 methods)?
Thank you.</p>
