Apple tvOS Build Generation

I want to export my game for tvOS platform. This is first time for me so I have so many questions, I used google for this purpose but could not able to find satisfactory resource for this.

Actually I exported build but no icon I found in apple tv and with just static main menu screen in front of me.
So I need to solve all this point to launch this game.

If any tutorial is available that provide guidance with Unity export build for tvOS then it is really great.
As well I already read most resources available and last I read this one.

https://developer.apple.com/tvos/human-interface-guidelines/

First point to discuss is, how many resources are require for icon and top shelf?
All these images are in which resolutions?

Just one, but you can add up to five if you want a parallax effect. Just make sure the upper layers have transparent backgrounds, and the bottom layer is opaque.

I want to add 5 images so in what size I need to create those?
Please provide me guidance for that.

As per my reading, I have summarised 3 resolutions.

App Icon
Small Icon
400x240
Large Icon
1280x768

Top Self Image
1920x720

Sounds about right to me. These are the layers:

++++Transparent Image (Closest to you)
+++Transparent Image
++Transparent Image
+Transparent Image
Opaque Image (Furthest from you)

Okay here are only 3 resolutions images I have mentioned what are other?

@_Daniel , do you have launched any game in tvOS? Because I really need your help in this.

What sizes are required for all these?

You already said the resolutions in your previous post.

@_Daniel Yes I realise this thing later on. That I have mentioned correct resolutions only those I need to use.
Can I ask one more question? How many layers need to create for each sections of icon submission?

The maximum is 5.
