Marshal/export feature

[Jordan-Mesches]

I'm currently using AWS lambda, and I'm trying to use this library to interact with some gsuite products. So naturally I want to split up different parts of my project as to embrace micro service architecture that comes with lambda. So here comes my problem, I want to have a Authenticator lambda that can return Authentication to other lambdas, however when using service_account_creds.with_subject(admin-email) it returns a google.oauth2.service_account.Credentialsobject. Now this is great however I'm not able to return this in my lambda, and my attempts at marshaling it myself have failed. So it'd be great if their was a feature to either Marshall the object, or like export it to Json or something like that.

Also if does already exist sorry, I was unable to find it anywhere.
