in the accounting dashboard, how can I tell if one journal or another was selected. How to know if the invoice journal or a credit memo journal was selected, I need to take an action according to the selected journal.

I located the action of the button, but I don't identify where the sales journal differs.

<t t-name="JournalBodySalePurchase" id="account.JournalBodySalePurchase">
                        <div class="col-xs-6 o_kanban_primary_left">
                            <t t-if="journal_type == 'sale'">
                                <button type="object" name="action_boleta_venta1" class="btn btn-primary btn-sm o_invoice_new">
                                    <span>New Inv444444oice</span>
                                </button>
                            </t>

Please your support.
