How do I cast the audio from my Shield TV to my Google Home (pair stereo group)?

I enable Bluetooth on the Speaker, on the Shield TV I can see the Group Speaker, but it does not enable to pair.

Any help?

I had to join the Chromecast built in beta for it to work for me  https://play.google.com/store/apps/details?id=com.google.android.apps.mediashell

I joined the Chromecast built-in beta and I was able to pair my stereo speaker (both GH), but it was difficult, even with just one I was not able to pair it, what I did was put it to pair, and I select my Stereo Speaker, when it was written pairing I restarted my Shield TV, and when reboot it was connected. The two speakers were working together, but the audio is out of sync, my Anker Bluetooth speaker works normal
