I searched around and did not see an answer. I have been running gam 3.65 for sometime. Looks like things changed in 3.8 and later.
My gam 3.65 has an oauth2.txt and admin-settings-v1.json which I think make things work. I see the newer versions have a
client_secrets.json and oauth2service.json file. Also looks like the gam utilitiy is now an executable and not a gam.py python program.
I need to do more digging but was hoping someone had some steps to install the new gam along side my existing gam, I rely on it heavily, (great utility!).
If I follow the instructions for the new gam configuration I want to make sure not to break my existing configuration.
