+To display the user's information, you can use the `logtoClient.getIdTokenClaims()` method. For example, in your Home page:
+
+### Request additional claims
+
+<FindUserInfoMissing method="getIdTokenClaims()" />
+
+<ScopesAndClaimsIntroduction />
+
+To request additional scopes, you can configure the Logto configs:

+```js title="index.js"
+import LogtoClient, { UserScope } from '@logto/browser';
+
+const logtoClient = new LogtoClient({

+    UserScope.CustomData,
+    UserScope.Identities,
+    UserScope.Organizations,
+  ],
+});
+```
+
+Then you can access the additional claims in the return value of `logtoClient.getIdTokenClaims()`:
+
+```ts
+const claims = await getIdTokenClaims();
+// Now you can access additional claims `claims.email`, `claims.phone`, etc.
