Question Simple 3D plane reflection effect shader graph

Hello,

i was trying to create a basic reflection, this is what I was thinking:

1) Use the first person camera to generare a render texture,
2) Import as a texture 2D inside the shader
3) Reflect the uv to flip the image
4) Missing: i need a way to deform the image probably using a matrix transformation to rotate the mirror plane 90 degree but I didn't find a clue how to generate and use it on shader graph.

thanks in advance,
