Debugging CUDA DLL with Nsight extension on VS2019

HI
Trying to debug a DLL written with VS2019 as a CUDA project.
This DLL is part of IG engine.
I couldn’t find a way to attach (or run) VS2019 Nsight debugger extension to the EXE (IG Engine) that runs the DLL. Nsight extension is trying to run the DLL which of course fails.

Does any one know of a technic to debug a CUDA DLL with Nsight?

Thanks.
Tamir,
