Create XML File Under **static/src/base.xml** in your module and add this code:

    <templates>
            <t t-extend="Sidebar">
                <t t-jquery="a.oe_sidebar_action_a" t-operation="replace">
                    <t t-if="widget.session.uid !== 1">
                    <a t-if="item.label !== 'Export'" class="oe_sidebar_action_a" t-att-title="item.title or ''" t-att-data-section="section.name" t-att-data-index="item_index" t-att-href="item.url" target="_blank">
                         <t t-raw="item.label"/>
                     </a>
                    </t>
                    <t t-if="widget.session.uid === 1">
                        <a class="oe_sidebar_action_a" t-att-title="item.title or ''" t-att-data-section="section.name" t-att-data-index="item_index" t-att-href="item.url" target="_blank">
                             <t t-raw="item.label"/>
                        </a>
                    </t>
                </t>
            </t>
    </templates>

Add this in File **__openerp__.py**:

    'qweb': [ 
        "static/src/base.xml", 
    ]

 

Now restart the server and update your database and refresh the page.
