Could you use this logic to just assign 'access_token' or 'refresh_token' to a variable that gets used here rather than repeating the logic for each field?

[AlyssaWang]

Yep totally works -- updated.

[Jammjammjamm]

This isn't just for backend services, though, it's for everything, right?

[AlyssaWang]

Sort of? I named it that since it stipulates backend_services in the check itself but I think this could be better named regardless -- updated.
