Unity Shader Graph for Triggered Transparency

I'm in immediate need of a Unity 2022.3 developer to craft a custom shader using Shader Graph. This shader will apply a unique visual effect: making only the polygons of a game object transparent when they intersect with a specific volume [gameobject trigger zone].

Key requirements and details include:
- The shader should trigger the transparency effect when the game object's polygons intersect with a defined volume in the game.
IMORTANT: NOT ALL THE GAMEOBJECT , ONLY THE POLIGONS THAT ENTER TO THE ZONE
-
- The transparency effect will involve the affected polygons becoming 90% transparent.
and control in inspector the transparency start in 90%
- The transition to this transparency is expected to be immediate, not a gradual fade-in.

The ideal candidate should have:
- Proficiency in Shader Graph and Unity.
- Prior experience creating custom shaders, particularly those that involve trigger-based effects.
- A good understanding of visual effects in games and how to implement them efficiently.

this scene is using URP and will use for apple vision pro scene.
in fact the scene to work is already prepared for vision OS.
