LPE expression to isolate one object indirect reflection

My salutations;
I have this rocket separated into basic geometry nodes in the scene and this is the final render.
My goal is to render the indirect reflection of each object of the rocket on the rest of the objects.
This is the indirect reflection of all the objects.
I have tried LPE (Light Path Expressions) to achieve this but this is my first time using LPE.
I'm a little bit confused about the syntax and different variables.
I have assigned an LPE Tag for each object in the scene.
I tried this expression "lpe:G+'fins'L" to isolate diffuse and glossy bounces of the fins (colored in red) but I get nothing (empty image) when I visualize that pass in Mplay.
So what's the right expression to isolate the indirect reflection of the red fines on the rest of the parts of the rocket?
Thank you for putting the time to read this post.
I really appreciate your help.
