I've already replaced footer on other pages with custom one (by defining extension on src/main/amp/config/alfresco/site-data/extensions), but seems like it doesn't affect footer on faceted-search page. How can I customize this footer? Should I define another extension or I can somehow use existing one?
On the image are my extension files (+ css in .../web/components/footer).

And footer.get.html.ftl
<@markup id="additional-footer" target="css" action="replace" scope="global" >
<@link href="${url.context}/res/components/footer/footer.css" group="upload"/>
</@>
<@markup id="additional-footer" target="html" action="replace" scope="global">
<@uniqueIdDiv>
<div class="footer footer-com">
<span class="copyright">
<span>${msg("label.copyright")}</span>
</span>
<br/>
<span class="copyright-additional">
<span>${msg("label.copyright.additional")}</span>
</span>
</div>
</@>
</@markup>
