Sorry, do you mean a link to a Roku TV? Assuming you mean a link to Projectivity, here’s a link:

You can scroll to the bottom - basically you should just be able to enable installation from third party sources in your Google TV android options, and install the APK. I don’t have Google TV, but worked fine on Android TV. I forget if you have to fiddle with any other settings to get it to boot into Projectivity, or if you just change the launcher app in settings.
Logan Paul edition… Just wow.
