I want to add the item  action_invoice_cancel (Invoice Cancel) button in the  customer invoice . My aim is to see that button only for the users in the sale_manager. I tried like this:

Code

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="orchid_invoice_cancel_request_inherit" model="ir.ui.view">
        <field name="name">invoice_cancel_request</field>
        <field name="model">account.invoice</field>
        <field name="inherit_id" ref="account.invoice_form"/>
        <field name="arch" type="xml">
             <button name="action_invoice_cancel" position="after">
                <button string="Cancel Request" type="object" name="cancel_request" attrs="{'invisible':[('state','not in',('open','paid'))]}"/>
             </button>
             <field name = "move_id" position="after">
                <field name = "od_cancel_reason" />
             </field>

             <button name="action_invoice_cancel" position="replace">
                <button name="action_invoice_cancel" type="object" states="draft,proforma2,open" string="Cancel Invoice" groups="base.group_no_one,sales_team.group_sale_manager"/>
             </button>

        </field>
    </record>
</odoo>

But its not working. What to do? Thanks in advance.
