I'd like any button on my Sony XBR X900E 's remote to start YouTube TV. It's this remote. There is both a TV button and unbound extra buttons (colored), but I've been unable to figure out how to bind either of them to YouTube TV.

I've been through the options a few times now and couldn't figure out how to bind a button to YouTube TV. There is a setting path to look for additional "live TV" apps to populate channels, but it fails with an error & says to try again. Any guides or links that explain how to do this, or is it impossible? Let me know if this belongs elsewhere (like in a Youtube TV sub) and I'll delete the post. Thanks.
