Add glow effect on line of my shader

Oh yes it’s true that the glow is much better managed on yours ! Thank you very much! It’s great to have some advice from you!

I had a question! Is it possible to put a shader on a material that is transparent?That is to say that we could have this luminescent square on a transparent plane and underneath another object that we would see through the transparent plane. I don’t know if I’m making myself clear…
