Is it possible to detect when a node module is running as a Google Cloud Function?

Is there any way to check if a node function/module is running as a Google Cloud Function other than setting an environment variable via the console and checking for that?

Example

// Other variables FUNCTION_REGION, FUNCTION_IDENTITY, FUNCTION_TIMEOUT_SEC, etc;
const isGoogleCloudEnv = !!process.env.GCP_PROJECT
