+### Using Auth Middleware
+
+If your Backstage instance uses service-to-service authentication you can pass an optional tokenManager to the collator factory. This will ensure that the collator makes authenticated requests to the explore backend.
+
+```tsx
+indexBuilder.addCollator({
+  schedule: every10MinutesSchedule,
+  factory: ToolDocumentCollatorFactory.fromConfig(env.config, {
+    discovery: env.discovery,
+    logger: env.logger,
