I am migrating a odoo 18 module to odoo19 but this view is available on 18 but it hasn't in 19 what can i do?? I thought First find this view on odoo18 and then think to find a solution?

My full view file is ,

<record id="view_attendance_overtime_tree" model="ir.ui.view">
    <field name="name">hr.attendance.overtime.view.tree.inherit.hr_overtime</field>
    <field name="model">hr.attendance.overtime</field>
    <field name="inherit_id" ref="hr_attendance.view_attendance_overtime_tree"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='employee_id']" position="after">
            <field name="positive_extra_hours" widget="float_time"/>
            <field name="negative_extra_hours" widget="float_time"/>
            <field name="overtime_status" widget="badge" decoration-warning="overtime_status == 'to_approve'" decoration-success="overtime_status == 'approved'" decoration-danger="overtime_status == 'refused'"/>
            <field name="double_overtime" widget="boolean_toggle"/>
        </xpath>
        <xpath expr="//field[@name='duration']" position="replace">

        </xpath>
    </field>
</record>

Now , I want to know,
1) How to navigate this view(hr_attendance_overtime_tree) location in odoo 18?

2) What can I do to migrate this view to odoo 19?( even this view not in default core module, so i cannot inherit no??

3) What is the purpose of this view? for what??
