I need to show attachments in kanban view.

<record id="view_document_ir_attachment_kanban" model="ir.ui.view">
        <field name="name">ir.attachment.kanban</field>
        <field name="model">ir.attachment</field>
        <field name="arch" type="xml">
            <kanban create="false">
                <field name="name" />
                <field name="datas" />
                <templates>
                    <t t-name="kanban-box">
                        <div style="width: 100px;">
                            <field name="name" />
                            <field name="data"/>
                        </div>
                    </t>
                </templates>
            </kanban>
        </field>
    </record>

Here field data is the binary field.
