google sign in fail
Sign in with Google temporarily disabled for this app
You should be able to create your own credentials and use them instead: https://github.com/harababurel/gcsf/blob/b198d66cf9f60983c15b855ff52efe35efd891f6/sample_config.toml#L58-L60
Is it possible to have clearer information about that? The API console is huge and asks an insane amount of things for which I have no clue how to proceed or fill.
First you have to setup new project, then add OAuth credentials. Here are a couple of screenshots:

@mknapik Thanks for the screenshots
@ranisalt This is consistent with my experience as well, I had trouble navigating the API console when first creating the credentials for this app. It's also the reason why signing in still doesn't work -- fixing it seemed like a chore and I never got around to it.
I'll try to get it working this week and possibly update the docs for users who want to manage their own credentials.
