locator function for RFD8500

i need to make a simple locator function, very much like the mobile version whereas the barcode serial is entered and beep based on the rssi value. (windows)

i am using an RFD8500.

using the demo app code (C#) from:


however, i cant find any documentation in which i can use make my window app do the locator function as the demo app code is only able to detect unique serials.

does anyone know how to do this with the RFD8500 in C#? or must i use the window UWP code to do this? e.g.
