When configuring an outbound Media Node, you can choose the source of the media file you want to share with your customers (API or Assets).
If you select Assets, you have the option to upload a new media file or select one that you've already uploaded into your Assets library. If you upload a new media file, this file is automatically added to your Assets library for future use.
Select Assets library from the left panel.
From here you can view, add, edit, and delete media files.
