[sylpheed:37184] Gmail AOuth2

 I was using Sylpheed for years, but then the cert problems (still there) and one account that requires AOuth2 had me switched to Claws. Claws is a mess, so I'm trying to set up AOuth2 on Sylpheed but so for keep failing. I have used the client credentials that work with Claws, and this is where I’m stuck. I’m on Windows 10.
 Here’s my aouth2.ini (located in 'C:\Program Files (x86)\Sylpheed\'):
--- aouth2.ini ---
[*@gmail.com]
client_id=<client_id>
client_secret=<client_secret>
scope=https://mail.google.com/
auth_uri=https://accounts.google.com/o/oauth2/auth
token_uri=https://oauth2.googleapis.com/token
--- end ---
…and this is the log output:
--- start ---
