 Important: If you're uploading your build, set `Compression Format` to `Disabled` in `Player Settings` > `Publishing Settings`.
 
-Please note that Embedded Wallets (OAuth version) may not work when testing locally using Unity's default Build and Run feature for WebGL.
+Please note that In-App Wallets (OAuth) and Coinbase (Smart Wallet) will not work with default `Build and Run` when testing **locally**.
 
 You must host the build or run it locally yourself after adding the `Cross-Origin-Opener-Policy` header and setting it to `same-origin-allow-popups`.
 
 Here's a simple way to do so, assuming you are in your WebGL build output folder:
 
-```csharp
+```js
+// server.js
 const express = require('express');
 const app = express();
 const port = 8000;

 ```
 
 Once again, please note that no action is needed for hosted builds.
