Work flow analyzer custom rules

I am creating a new custom rule for work flow analyzer “ST-NMG-010” which validates the Boolean variable name in any of the activities in UIPATH project.
Earlier I struggled to compile the code in Visual studio for the new rule “ST-NMG-010” I have created in C#.
However I am able to successfully compiled the code and able to create the DLL.
I copied the DLL in correct paths and updated the file to include the rule.

But the new rule is not visible in the work flow analyzer and I am not sure how to proceed further on it.
It is hindering my testing in UIPATH studio 2019.10

I am using visual studio 2019 & UIPATH 2019.4
