How to use the @hint/utils-json.finalConfig function in @hint/utils-json

// When using local connector to read local files, 'content' is empty.
            let result = parseJSON(response.body.content, 'extends');

            if (isPackageJson && !result.data.babel) {
                return;

            await this.engine.emitAsync('parse::start::babel-config', { resource });

            // `result.scope('babel')` won't be null since `result.data.babel` was confirmed to exist above.
            result = isPackageJson ? result.scope('babel')! : result;
            config = result.data;

            const originalConfig: BabelConfig = cloneDeep(config);

            const finalConfig = calculateFinalConfig(config, resource);

            if (finalConfig instanceof Error) {
                await this.engine.emitAsync(`parse::error::babel-config::extends`,
                    {
                        error: finalConfig,
                        getLocation: result.getLocation,
                        resource
                    });

                return;
            }

            if (!finalConfig) {
                return;
