I see, sorry, I misunderstood you before.
This is indeed documented here:
https://vpaas.kaltura.com/documentation/Mobile-Video-Player-SDKs/AndroidChromeCast_V3.html

and should perhaps be documented here as well:
https://vpaas.kaltura.com/documentation/Mobile-Video-Player-SDKs/iOS-Casting-Chromecast.html

This documentation is kept on our GitHub repo here:
