To use a backend service to opt into using scopes when the global Scopes setting is
Enforced:
Prepare your authorized app for scopes. This process is dependent on the type
of app being used.
Navigate to IFS.
Select the service accounts used by your backend service.
Attach the scopes required for your Backend Service to the service
account.
Note: For ION, all service accounts used from this app must have scopes
enabled. In the case of ION, this means that all service accounts used in
all documentation and workflows must be modified to include ION in their
scopes.
