Call Addon methods in C# OpenSDK

I’m using TestProject.OpenSDK 1.2.4 in C#. How do I use the addons method in the C# script?

I’m seeing this below code for swipe when i record the swipe action using recorder. But this method not available in the testproject open sdk. so is there anyway we can access/call these add on methods in our c# project?

boolResult = driver.TestProject().SwipeGesture(913, 1503, 111, 1487, 300);
