>>>I found the class for this button, but I'm not sure what should I do.

Once you have found the class, you need to look and see what it's namespace is and what Project it is in.

Then go to the project you are trying to use it in and right click reference/add reference. Go to the projects tab and add that project.

Then you need a using direct with the namespace you found in your class file.
