Xfinity Stream App Missing From Troypoint Tool Box

I just purchased the New Walmart box and want to install the Xfinity stream app. It is not listed in the new Troypoint Toolbox. Where can I find it?

look in the play store

Xfinity Stream - Apps on Google Play

It’s not in the Play store because the box has Android TV.
