Presentation API sample from Android Chrome

Is the [Presentation API sample](https://googlechrome.github.io/samples/presentation-api/index.html) intended to work on Android Chrome? On desktop Chrome it pops up the Google Cast extension, but on Android I get "no screens found". Secondarily, if it should work on Android, how does Android know about a second screen? I've got an Amazon Fire Stick and an ezCast device here, as well as miracast software running on a server; is there some specific thing those devices need to advertise so that the Presentation API stuff in Chrome notices that they exist and offers them as a target?

(I think this might be a @beaufortfrancois question, although of course I'm happy to hear from anybody :-))
