Play/Pause chromecast through alexa

The Chromecast Bindings addon has a channel called “control” of type “player” which seems to support Play and Pause.

I got the volume control working as its just set up as a “dimmer” with the tag [ “switchable” ]

Dimmer LivingRoomChromecastVolume "Chromecast Volume" <soundvolume> [ "Switchable" ] { channel="chromecast:chromecast:XXXX:volume" }

I could not find the appropriate tag to let my alexa app find the player

Player LivingRoomChromecastControl "Chromecast Control" <mediacontrol> { channel="chromecast:chromecast:XXXX:control" }

Is that even possible?
