+If you are using deep links on your own platforms (websites, discords, etc), we kindly ask that you insert the appropriate

+additional functionality in the future.
+
+For more information on UTM parameters, please visit [Google's Campaign URL Builder](https://ga-dev-tools.google/campaign-url-builder/)
