🎥 Describe the feature you'd like to request

Per @dylanjha :

Usage with query params

• Mux supports a number of query params on stream.mux.com URLs (the most common being token= for signed URLs)
• When using the playback-id shorthand, we'll need to support query params so that playback-id="abc123?token=xyz789" gets expanded to a src that looks like https://stream.mux.com/abc123.m3u8?token=xyz789

For a more detailed example, see e.g. Secure Video Playback
