I am using odoo 17, I have a form view for managing bank transactions. I want the credit and debit fields to be visible when creating a new transaction. However, after saving the transaction, I want these fields to be hidden and no longer visible on the form.

here's the form view:

<record id="view_oui_finance_transaction_form" model="ir.ui.view">
    <field name="name">oui.finance.transaction.form</field>
    <field name="model">oui.finance.transaction</field>
    <field name="arch" type="xml">
        <form string="Transactions">
            <sheet>
                <div class="oe_title">
                    <label for="reference" class="oe_edit_only"/>
                    <h1><field name="reference"/></h1>
                </div>
                <group>
                    <group>
                        <field name="date"/>
                        <field name="debit" modifiers="{'invisible': [['__mode', '!=', 'create']]}"/>
                        <field name="operation"/>
                    </group>
                    <group>
                        <field name="value_date"/>
                        <field name="credit" modifiers="{'invisible': [['__mode', '!=', 'create']]}"/>
                        <field name="account_id"/>
                    </group>
                </group>
            </sheet>
        </form>
    </field>
</record>
