Ring on fire tv

I am trying to get my cameras to go on my fire tv,This hard to explain Th cameras are on the fire tvI press the alexa voice button and say show me the front door and it does, I have set up routines so that when the camera detects it will show on the tv but it doesn't Also if a ask my alexa speaker show me the front door it just says I don't know what when wrong there sending to tv, it doesn't do anything.So what I am trying to say is if someone is detected at my door why won't it come up on my tv
