Roku Voice remote pro compatibility

I'm pretty sure it is, but if you go to https://www.roku.com/products/accessories/roku-voice-remote-pro when you're logged into the Roku account (at https://my.roku.com) that the 4660 is linked to it should tell you that it is as well as any other Roku devices that are linked to that same account.  It's compatible with my Roku 3 and that's more than 10 years old.
