in Studio, if you add the particular Technology bundle as dependency (here Windows),
then you can navigate and see your function listed under
Dependency -> Windows (Project) -> Windows (entity)-> Functions -> <your function name>
You can view the name, caption, input parameters and output paramters [except Code]
In some cases, If the function is in abstract level, you may need to check in Operating System bundle functions list.
Also ensure the version of bundle while adding as dependency, otherwise you may not be able to find the function.
Hope it helps 🙂
