Sending gmail with oauth2

[Schaumburg Samuel]

Hey there,

I wonder if there is a way to make mu4e work with google oauth2.

I have used a setup as described in the manual, using smtpmail-send-it
for sending mail. I fetch mail with offlineimap, which I made to work
with google oauth2.

Here's the code concerning sendmail:
(setq message-send-mail-function 'smtpmail-send-it
     smtpmail-stream-type 'starttls
     smtpmail-default-smtp-server "smtp.gmail.com"
     smtpmail-smtp-server "smtp.gmail.com"
     smtpmail-smtp-service 587)

However, this is not working, because google is not accepting the
credentials this way.

Does anybody know, if it is possible to set up smtpmail to also work
with oauth2 ?

Since I am not that good with lisp, I would be happy if anybody had a
code snippet I could use to make that work.

I have the following function for sending email via gmail, and it works:

(setq message-send-mail-function 'smtpmail-send-it
starttls-use-gnutls t
smtpmail-starttls-credentials '(("smtp.gmail.com" 587 nil nil))

smtpmail-default-smtp-server "smtp.gmail.com"
smtpmail-smtp-server "smtp.gmail.com"
smtpmail-smtp-service 587

smtpmail-debug-info t)

With credentials in ~/.authinfo.

I think I might have found out how to do it at https://www.emacswiki.org/emacs/SendingMail

This is not working.
First of all credentials in .authinfo are not loaded and have to be typed in manually.
When trying to connect this is the error message returned, saying that google is refusing to connect.
As I said, I need smtpmail to not use plain authentication, but oauth2.
