+
+Add support for auth_tokens in boot and update methods, plus a setAuthTokens method
+
+Users can now pass authentication tokens to Intercom for secure data operations. The `authTokens` property accepts an object with any string key-value pairs, and the `setAuthTokens` method refreshes them at runtime without a full update.
+
+Example usage:
+```js
+boot({
+  email: 'john.doe@example.com',
+  userId: '9876',
+  authTokens: {
+    security_token: 'abc...' // JWT
+  }
+})
+```

+ #### Authentication tokens
+ For secure data operations, you can pass authentication tokens to Intercom using the `authTokens` property. This accepts an object with any string key-value pairs.
+
+ ```ts
+ const { boot } = useIntercom();
+
+ boot({
+  email: 'john.doe@example.com',
+  userId: '9876',
+  authTokens: {
+    security_token: 'abc...', // JWT token
+    api_token: 'xyz...',
+    // Any other tokens as key-value pairs
+  }
+})
+ ```
+
+This is distinct from `intercomUserJwt`, which is for Messenger identity verification. To refresh a token during a session without sending a full `update`, use the `setAuthTokens` method:
+
+```ts
+const { setAuthTokens } = useIntercom();
+
+setAuthTokens({ security_token: 'refreshed-jwt' });
+```
+
