override the corresponding environment variable.

Security Note: Care should be taken to not expose the auth token for this
handler by specifying it on the command line or by directly setting the
environment variable in the handler definition. It is suggested to make use of
secrets management to surface it as an environment variable. The handler
definition above references it as a secret. Below is an example secrets
definition that make use of the built-in env secrets provider.
