#employee.message_post(
# message_type='notification',
# body=body,
# subject=title,
# subtype_xmlid="mail.mt_comment",
# res_partner_id=employee.user_id.id,

this way, the notification is going as an email, but not getting any popup at the "conversation" window at the top right of module(beside activity and reminder)

Any suggestion how to do that?
