Launch my App Activity on Home key pressed

Question

I am developing a Launcher app for Android TV and want to override the functionality of Home button. I want to bring my Application's Activity to top when Home button is pressed so that it acts as default launcher. I tried this Android Studio TV remote buttons but did not work. It is definitely possible because there are button mapper apps on the PlayStore. I have this in my AndroidManifest.xml
