Hi,

Please search for the record XML id "portal_service_category" in your code. you can get the corresponding my/ticket record

<div id="portal_service_category" position="inside">
<t t-call="portal.portal_docs_entry">
<t t-set="icon" t-value="'/helpdesk/static/src/img/tickets.svg'"/>
                <t t-set="title">Tickets</t>
                <t t-set="text">Follow all your helpdesk tickets</t>
                <t t-set="url" t-value="'/my/tickets'"/>
                <t t-set="placeholder_count" t-value="'ticket_count'"/>
            </t>
        </div>

Hope it helps
