Help!

Fedora 31
curl-7.66.0-1.fc31.x86_6

gMail: less secure apps are purposefully off as gMail will be dropping 
support for less secure in June.

I can not find anything our there on how to use curl with
gmail and OAuth2.

I did figure out how to get my token:

   First, you must obtain your Client ID and Client Secret by using
   a browser.  Open the following

      https://console.developers.google.com/
      --> Credentials (left column)
        --> "+ Create Credentials"  (button at the top)
           --> OAuth client ID
             --> Application Type = Web Application
               --> Name: give it a unique name
                 --> Save
                   --> copy the resulting Client ID and Client Secret
                       into the corresponding variables below.
                       And independently save these values as well

   The script will then take you to a browser page where you will
   sign into your google account to receive your
   authorization code, which you save

   Also note that you have to tell gmail that the suspecious activity is 
you.
   gmail will send you a letter with a link to follow


client_id="aaaa"  # from the web page
client_secret="bbb" # also from the web page
scope="https://www.googleapis.com/auth/drive"
endpoint="https://accounts.google.com/o/oauth2/auth"=code&scope=$scope%access_type=offline&redirect_uri=urn:ietf:wg:oauth:2.0:oob"
 url="$endpoint?client_id=$client_id&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=$scope&response_type=code"




This is what I have so far

$ cat mail.txt | curl -vvv smtp://smtp.gmail.com:465 --mail-from 
"xxxx@gmail.com" --mail-rcpt "yyyy@zoho.com" --ssl -u 
xxxx@gmail.com:'zzzz' -oauth2-bearer 'big long thing'
