You will probably find it easiest to update to buster which contains getmail5. If I'm not mistaken stretch has getmail4 and it doesn't include the script named "getmail-gmail-xoauth-tokens" that you need to run in order to use oauth2. I can't say whether the script would work with getmail4 or not.
Beware, however of getmail6 which automatically installs itself if you update to bullseye. It is not real getmail. It is a confusingly titled fork of getmail which was done to to make it work with python3. It is not supported by the original author of getmail who gives great support for getmail5. There is a mailing list for support of getmail. The website for getmail is: https://pyropus.ca./software/getmail/. It contains very complete documentation and a link to the support mailing list.
