 You can also pass the identifiers in the `plugSDK.init` option without generating the session token.

 You can add or update the data in `user_traits` by using the `updateIdentity` method on the PLuG SDK. Attached is a sample code snippet for the same. 
 
 ```jsx
 window.plugSDK.updateIdentity({
-    user_traits?: {
-    custom_fields?: object;
-    display_name?: string;
-    email?: string;
-    phone_numbers?: string[];
- };
+  user_traits: {
+    custom_fields?: object; // optional
+    display_name?: string; // optional
+    email?: string; // optional
+    phone_numbers?: string[]; // optional
+  }
 })
