All the examples of getting access to a google api (in my case, the calendar api) uses the google sign-in api (which produces a UX for selecting the account).
In my case, I have a toy app that wants to use a private calendar as a resource for that app. The resource isn't available to a user of the app (even if I wanted to use the sign-in approach).
I need a way of selecting, internally, a google account with an email_account and password.
I can't seem to find out if this kind of approach is allowed or not and if it's allowed how do I code for that.
Thanks in advance.
