How to send DRM license from sender app (Android) to custom receiver (Chromecast)?

I'm trying to stream Widevine DRM content from an Android app to Chromecast with custom receiver (CAF), but I don't know how to dynamically set the license url.

In the receiver example below the license is hardcoded, but I need to send it as a parameter from the sender app to the receiver app. 

<html>
<head>
  <script type="text/javascript" src="//www.gstatic.com/cast/sdk/libs/caf_receiver/v3/cast_receiver_framework.js">
  </script>
</head>
<body>
  <cast-media-player></cast-media-player>
  <script>
    //cast.framework.CastReceiverContext.getInstance().start();

    const context = cast.framework.CastReceiverContext.getInstance();
    const playbackConfig = new cast.framework.PlaybackConfig();
    //Widevine license URL
    playbackConfig.licenseUrl = 'http://10.4.251.23:8094/license';
    context.start({playbackConfig: playbackConfig});

  </script>
</body>
</html>

Here's the sender app (Android):

String mStreamUrl = getStreamUrl();
String licenseUrl = getLicenseUrl();

MediaMetadata movieMetadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_MOVIE);

movieMetadata.putString(MediaMetadata.KEY_TITLE, childTitle.getName());
movieMetadata.addImage(new WebImage(Uri.parse(childTitle.getBackgrounImage())));

return new MediaInfo.Builder(mStreamUrl)
        .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
        .setContentType("video/mp4")
        .setMetadata(movieMetadata)
        .build();

}

The MediaInfo.Builder allows you send custom data in JSON format also using this method

public MediaInfo.Builder setCustomData (JSONObject customData)
