Home Assistant set up prompt

I just have the Optik TV installed, but every time I turn the 4K PVR on, a prompt comes up on the screen saying something like "To connect Home Assistant, press OK". Since I do not have Google Home, I just ignore the prompt and go to the Guide right away.  However, the prompt stays at the background and does not go away until I start to watch live TV or a pre-recorded program.  This is pretty anonying.

Can someone tell me how to switch off the prompt?
