Compare Random Vector to Camera Vector to create Glitter Effect

Hello, how would you make a Shader that compares a random Vector baked into a Texture (just some random noise colors) to the Camera Vector to generete a kind of Glitter effect? I tried to do it like that but it didn’t worked correctly, it just did the effect in one axis. And when I would turn around with the camera as seen in the Gif there just would be no glitter at all.
