Does the Adult Swim iOS app support Chromecast?

I want to stream Rick and Morty to my Chromecast from the Adult Swim iOS app. However, unlike most media apps, the Adult Swim app doesn't seem to be detecting my Chromecast automatically. **Is it possible to stream Adult Swim shows to a Chromecast from an iPhone?** Note: I am aware that developers need to manually add Chromecast support to an app for it to be streamed. However, it seems like an odd omission when Adult Swim's sister app *Cartoon Network* was recently updated to add Chromecast support.
