Hi,
I need to add a button below the download button in the sale order portal view. But It appears near the download button.My xml code is given below:

<template id="sale_order_portal_id" name="sale_order_portal" inherit_id="sale.sale_order_portal_template">
            <xpath expr="//div[hasclass('o_download_pdf')]" position="inside"
                        <div class="btn-group flex-grow-1 mr-1 mb-1">
                        <a class="btn btn-secondary btn-block o_download_btn"  t-att-href="sale_order.get_portal_url(report_type='pdf', download=True)" title="Download"><i class="fa fa-download"/> Download</a>
                        </div>
               </xpath>
 </template>
