Is your feature request related to a problem? Please describe.
An Audio-On-Demand option with amplify video plugin will be a great help. This should create a separate set of resources and work side by side with VOD or LiveStream

Describe the solution you'd like
Based on the quick look I had with amplify-video github codebase, the VOD option code and template can be customized to quickly add this feature
