I have downloaded this component and open it in Integration studio. Here you can see the input parameter details, then if even you want to see the implementation then click on C# edit icon. You can see the implementation and check the possible values. I know if is difficult to understand about the sample values, but at least you can have a look here. I am not sure whether this will resolve your issue until the Forge component maker provide you the sample, but you can see and try to extract few things.

One more suggestion try to message the team
