 ## File downloads - advanced usage
 
-By default, the file `url` provided through `notifyUploadCompleted` method is used to trigger a file download. However, if you need to handle a download in a different way, you can provide a custom `downloadHandler` to ChatComposite. Next, we modify the `fileDownloadHandler` that we declared previously to check for an authorized user before allowing to download the file.
