Line of sight, seeing an obstacle?

I would like to know if it is possible to make the line of sight behaviour see an obstacle, not seeing through it, but just seeing it, the object doesn't have the obstacle visible in his line of sight, even though it logically should have it when it is blocking his view.

Use the "Is within angle" condition and set Within to 180?

the problem is that will let objects behind the obstacles be seen

Can you not check the range?

Can I have the use case to make sense of the problem in my head?

Basically, I want to see the wall so I can show it over a shadow (Z ordering modification based on the shadow caster), If I cannot see it but it is in my range, I want it to be placed under the shadow caster.

So if I can see it, I would make it visible, but if I cannot, making it invisible. I though of LOS since the shadow caster does not have the option to check what is under the shadow and what is not under it.

Now that i think about it, it is probably not the best way to do it.
