good afternoon to all, what is the view that has to be inherited to add a field in the detail of the invoice, model: account_invoice_line.

I am currently inheriting:

<field name = "model"> account.invoice </field>

<field name = "inherit_id" ref = "account.invoice_form" />

but the change is not reflected.

 <record model="ir.ui.view" id="e.view_account_invoice_mobile">

            <field name="name">Cambios en al vista de mobile de Invoice</field>

            <field name="model">account.invoice</field>

            <field name="inherit_id" ref="account.invoice_form"/>

            <field name="arch" type="xml">

               <xpath expr="//kanban[@class='o_kanban_mobile']" position="replace">

            <kanban class="o_kanban_mobile">

    --code

</kanban>

</xpath>

       </field>

        </record>
