 It's important to note that this setting is a sensitive credential, and as such, its value should be stored in a secure manner that matches the location specified in the `[global]` section's `credentials_location` setting. For example, if `credentials_location` is set to `"AWS_SSM"`, then the gcp_service_account_json_payload_value should be the name of an AWS Systems Manager Parameter Store SecureString parameter that contains the contents of the GCP service account key JSON file.
