I have a piece of codes to send an email to a user when he did made some choice on the website. The code use the following function to create the email

 http.request.env['mail.mail'].create(mail_values).send()

But it only works when I used admin to login, otherwise, I was given the error:

odoo.exceptions.AccessError: You are not allowed to create 'Outgoing Mails' (mail.mail) records.

This operation is allowed for the following groups:

        - Administration/Settings

I try to find option in settings to grant the permission of sending email to all user. But I cannot find such option. Please help me solve this issue. Thank you very much in advance.
