Use 2D Atlas and exclude used Textures from build

Hi, I am confused about how in Unity to use 2D Atlas and exclude used textures from the build.


For example, I have an animation Introduction with a lot of textures that I want to combine into 2D Sprite:

Here is what I have tried to do, but it hasn't helped:

I have created a "ResoursesExcluded" Folder in "Assets" and have put some textures that are used in Scene.
In the "Resources" Folder I have created a 2D Atlas file, that has textures from "ResoursesExcluded":

Atlas is Included in Build. But after creating the build, I have both textures and an atlas in the build (info from Editor.log):
1.6 kb 0.0% Assets/ResourcesExcluded/IntroAnimation/robot no hand.png
4.6 mb 0.3% Built-in Texture2D: sactx-0-8192x8192-Crunch-IntroAnimationAtlas-ed6aac96
100.5 kb 0.0% Assets/Resources/Textures/IntroAnimation/IntroAnimationAtlas.spriteatlas

How to use 2D Atlas and exclude textures/images from the build correctly?
