How to Chromecast Amazon on Nexus?

I've been struggling for a few days now trying to chromecast Amazon video from my Nexus. I've also been searching for just as long for a solution.

Most posts I come across state that chromecasting my entire screen from Google Home should work, but it doesn't. A lot of posts I'm finding are also pretty old so appear outdated.

The result from chromecasting my entire screen and playing an amazon video is just the audio comes over the cromecast, no video. The video just plays on the device.

If I play a YouTube video in that fashion, I do indeed get video and audio on both the TV and device.

To get this far, here's what I've done:

1 - Downloaded Google Home
2 - Downloaded Amazon Video app
3 - Launch Google Home and cast my screen
4 - Launch Amazon Video app

When setup like this, I can see the Amazon app on both the device and TV. But when I play a video, I get a blank screen and just audio on the TV, the video is playing on the device only.

Some information I found online is that the Amazon app blocks video from chromecasting from certain devices??

My device is a Nexus 5X running Android 8.0.0
