Controlling Chromecast over CEC with Kodi remote

The subject seems pretty obvious, is there some way to use kodi to send CEC commands to devices in the system?
I notice there’s such a thing as CECToggleState, but I’m not quite sure that actually tells a device to play? Or is that power toggle? Is there some other CEC command to tell a random device connected to my receiver to start playing?

WHY I want to do this: Want to use the (usb+rf) remote plugged into Kodi to control Chromecast play/pause
