Using Ray Detector feature within Ray Acoustics physics interface

Hello!
I've just started to dive into the Ray Acoustics interface by playing with the small_concert_hall file in the Application Library. There is one thing I would like to achieve and I could not figure out how to do it: In the Ray Trajectories plot, I would like to show only those rays which reach the set up receiver (a sphere). In the documentation, I found that a Ray Detector feature should be able to achieve it by filtering those rays in the filter node for the Ray Trajectories plot. How should I set up the expression in Filter to show me only the rays reaching the Ray Detector (receiver)?
Thanks a lot!
Kind regards Jan

You can see an example of how this in done here: https://www.comsol.com/model/ultrasonic-car-parking-sensor-68041 . See Results->Detected Ray Path->Ray Trajectories 1->Filter 1. There is a variable for this that is stored (in this case it is rac.rd1.rL). This can also be found if browsing Replace Expression->Component 2->Ray Acoustics->Ray Detector 1.
