Send an email in enqueued method

Hello, I am trying to send an email in an method enqueued with frappe.enqueue but nothing seems to work.

The method itself works properly and send an email with either frappe.sendmail( or make( when launched manually but when in enqueue nothing is sent.

The idea here is to send a confirmation email after an email absorption.
I use an enqueue to be able to get the recipient information after the communication is created (because appended documents are created before the communication so I must delay the treatment) and select the right answer.

Do you have any idea of a paramater or some way to allow background jobs to send an email ?
