Answer 1

The process which I follwed in my question is correct, it started working with this solution,

I was trying to override it in an existing module where I did other functionalities, but when I create a new module for overriding, it worked there. I don't know the difference between both of those modules but it solved my problem.

This answer is strange but it worked for me.
