Mouse actions not possible to perform on WPF/C# app

I tried to solve this problem on github, but response that I received seems to work on phyton, not on C#. Please have a look at this issue:

Is there a workaround for this in C# language?
Because I can’t find
"forceMjsonwp": True
And also I’m not 100% sure if my problem is same as issue, that I received in response on github.
