Add Command to Save Credentials During Linkage Process

[rodriguez03]

When linking a google sheet with python, it needs an OAuth credential in order to access it securely. The user needs to have a method and place in order to save these credentials.

Hello @rodriguez03, thanks for raising this issue. I agree that this is important to resolve.

I wanted to draw attention to the platformdirs package.
