Question Chroma Key Shader (Universal Render Pipeline)

Hello,

I'm new and don't have much programming or Unity experience. I used to edit my videos with the chroma key method and I really enjoyed it! But I don't know how to work with it in Unity. I already searched in other forum topics and found shaders, but after implementing into my Unity project, the shaders weren't compatible with the URP (even after updating the materials). I also bought a chroma key asset on the store, but it also doesn't work for me.

Is there any possibility to do this? I searched all the available chroma key topics in the Unity forum, but I couldn't find anything that works for me. I would just like to import a video into my game and change one background color (for example green) to a transparent one.

Greetings!
