Kodi on Chromecast

Hi. I own a Vizio M50-D with Vizio smart-cast/chrome-cast. I downloaded the Kodi app on the included Android tablet remote. I would like to know how to get the content from Kodi to be transmitted to the display. There seems to be no direct function/tab to have the content from the Kodi app in the tablet transmitted to the display. Can anyone assist me?
