IncrementalGenerator how to get unity project directory.

Unity Engine

I’m playing with IncrementalGenerator and what I need is to get my unity project directory and use it during
IIncrementalGenerator.Execute.

Actually path to anything inside my project would do, but best would be to have path to this generation dll.

I have tried to get path to my source generation assembly but unfortunately it is a shadow copy and what I get is:
AppData\Local\Temp\JB\AssemblyShadowCopies\1074c867fa904b9984860a5dab029b16\20\MyGenerator.dll

My last resort is to create *.dll.config for my dll but I would prefer a better solution.
