"UniveresalCanvasSubTarget could not be found" after importing Shadergraph Support Sample in Unity 2022.3

[Dunxter]

Describe the bug
After importing the ShaderGraph Support (Unity 6 URP) in my Unity 2022.3.62f3 project, the following compilation error appears:
Assets\Samples\UI Effect\5.10.8\ShaderGraph Support (Unity 6 URP)\UniversalUIEffectSubTarget.cs(12,49): error CS0246: The type or namespace name 'UniversalCanvasSubTarget' could not be found (are you missing a using directive or an assembly reference?).

I'm wondering if only Unity 6 has support for the ShaderGraph Support Sample?

To Reproduce
Steps to reproduce the behavior:

1. Start a 2022.3.62f3 Unity project
2. Import the UI Effect package and all required dependencies
3. Import the ShaderGraph Support (Unity 6 URP) sample

Expected behavior
Since there's not an specific Sample for Unity 2022 when it comes to ShaderGraph support, I was expecting this "ShaderGraph Support (Unity 6 URP)" Sample to work in my version (as UI Effect supports Unity 2022).

Environment (please complete the following information):

• UI Effect 5.10.8
• Platform: Windows Editor
• Unity version: 2022.3.62f3
• Build options: [e.g. IL2CPP, .Net 4.x, LWRP]

Thank you so much for your efforts and incredible package!
